PaperCut MF < 25.0.11 Path Traversal (CVE-2026-6418)

medium Nessus Plugin ID 313098

Synopsis

PaperCut MF installed on the remote Windows host is affected by a path traversal vulnerability.

Description

The version of PaperCut MF installed on the remote Windows host is prior to 25.0.11. It is, therefore, affected by a vulnerability:

 - A path traversal vulnerability exists in the Shared Account Synchronization component of PaperCut NG/MF. Due to a lack of proper path validation and sanitization, an authenticated user with administrative privileges could specify arbitrary file paths on the local file system. This allows for the enumeration of directory structures and the unauthorized reading of sensitive text-based configuration or system files. (CVE-2026-6418)

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 MF version 25.0.11 or later.
