Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

 - CGI versions before 5.00 for Perl return upload filenames with any client-supplied path, including ../ and Windows paths. The name returned for an uploaded file is the filename parameter of the part's Content- Disposition header, unchanged. An application that saves the upload under this name can be made to write outside the intended directory. (CVE-2026-120641)

Note that Nessus relies on the presence of the package as reported by the vendor.
