Users with Overall/Manage permission can instantiate any types related to configuration

Jenkins 2.575 and earlier, LTS 2.568.1 and earlier does not restrict the types of objects that can be instantiated as part of the project naming strategy configuration. This allows attackers with Overall/Manage permission to instantiate arbitrary types related to configuration, including those...

Link following vulnerability allows arbitrary file creation

Jenkins 2.575 and earlier, LTS 2.568.1 and earlier does not safely handle symbolic links with effectively empty names during the extraction of .tar and .tar.gz archives. This allows attackers able to control agent processes to provide crafted archives to the controller to write files to arbitrary...

Path traversal vulnerability in file parameters

Jenkins 2.575 and earlier, LTS 2.568.1 and earlier improperly identifies file paths attempting path traversal in file parameter names. This allows attackers with Item/Configure and Item/Build permission to write files to arbitrary locations on the controller file system, restricted only by file...

Improper handling of case sensitivity allows privilege escalation

Jenkins 2.575 and earlier, LTS 2.568.1 and earlier handles case-insensitivity in user names and group names inconsistently. While the canonical ID for a case-insensitive user or group name is created by lowercasing the name, comparisons of user names and group names are done using...

Missing permission checks in appscan allow enumerating credentials IDs

appscan 1.8.3 and earlier does not perform permission checks in multiple HTTP endpoints. This allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability...

Missing permission checks in xml-job-to-job-dsl

xml-job-to-job-dsl 0.1.13 and earlier does not perform permission checks, and makes its functionality available to users lacking Overall/Read permission. While only jobs the user has Item/Read permission for will be accessible, it does not require Item/Extended Read permission to convert their...
