critical Nessus Plugin ID 341348

Synopsis

PaperCut MF installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of PaperCut MF installed on the remote Windows host is prior to 24.1.9.76515 or 25.x prior to 25.0.12.76509, or 26.x prior to 26.0.4.76507. It is, therefore, affected by the following vulnerabilities:

- An authentication bypass vulnerability exists in the web management interface due to improper access controls. An unauthenticated, remote attacker can exploit this, to bypass authentication and modify certain system configurations. (CVE-2026-81578)

- A arbitrary code execution vulnerability exists in the database connection utilities due to improper validation against an allowlist of approved drivers. An authenticated, remote attacker can exploit this to execute arbitrary Java bytecode residing on the application classpath under the security context of the server process. (CVE-2026-82078)

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

Solution
