High Nessus Plugin ID 73862

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's different from CVSS.

VPR Score: 5.9


The remote web server uses a version of PHP that is potentially affected by a permission escalation vulnerability.


According to its banner, the version of PHP 5.4.x installed on the remote host is a version prior to 5.4.28. It is, therefore, potentially affected by a permission escalation vulnerability.

A flaw exists within the FastCGI Process Manager (FPM) when setting permissions for a Unix socket. This could allow a remote attacker to gain elevated privileges after gaining access to the socket.

Note that this plugin has not attempted to exploit this issue, but instead relied only on PHP's self-reported version number.


Upgrade to PHP version 5.4.28 or later.
