New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 7.4


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


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.


Upgrade to Plex Media Server version 1.19.3 or later.
