The version of RARLAB WinRAR installed on the remote Windows host is prior to 5.70 Beta 1. It is, therefore, affected by the following vulnerabilities :

  • An error exists in the file β€˜unacev2.dll’ related to the β€˜filename’ field, that allows a specially crafted ACE archive to overwrite files outside the destination folder. Such files could be in the system startup locations, and thus, lead to arbitrary code execution on next boot. (CVE-2018-20250)

  • An input-validation error exists in the file β€˜unacev2.dll’ related to handling ACE archives and filenames that allows path traversal pattern checking to be bypassed. (CVE-2018-20251)

  • An out-of-bounds write error exists related to handling ACE and RAR file parsing that allows arbitrary code execution. (CVE-2018-20252)

  • An out-of-bounds write error exists related to handling LHA and LZH file parsing that allows arbitrary code execution. (CVE-2018-20253)
