medium Nessus Plugin ID 244063

Synopsis

PaperCut NG installed on remote Windows host is affected by a vulnerability

Description

The version of PaperCut NG installed on the remote Windows host is affected by a vulnerability. A Path Traversal vulnerability exists in PaperCut NG before 22.1.1 and PaperCut MF before 22.1.1. Under specific conditions, this could potentially allow an authenticated attacker to achieve read-only access to the server's filesystem, because requests beginning with GET /ui/static/..//.. reach getStaticContent in UIContentResource.class in the static-content-files servlet.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PaperCut NG version 21.2.12, 22.1.1 or later.
