Plex Media Server < 1.19.3 Authenticated RCE

high Nessus Plugin ID 137326

Language:

Synopsis

A client-server media player running on the remote host is affected by a remote code execution vulnerability.

Description

According to its self-reported version number, the version of Plex Media Server installed on the remote Windows host is prior to 1.19.3. It is, therefore, affected by an authenticated remote code execution vulnerability in the camera upload feature. An authenticated, remote attacker can exploit this, by uploading a malicious file via the camera upload feature, to cause arbitrary python code to be executed in the context of the current OS user..

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

Solution

Upgrade to Plex Media Server version 1.19.3 or later.
