high Nessus Plugin ID 22310
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: 5.9


The remote web server contains a PHP script that is affected by a global variable overwriting vulnerability.


The version of PmWiki installed on the remote host contains a programming flaw in 'pmwiki.php' that may allow an unauthenticated remote attacker to overwrite global variables used by the application, which could in turn be exploited to execute arbitrary PHP code on the affected host, subject to the privileges of the web server user id.

Note that successful exploitation of this issue requires that PHP's 'register_globals' and 'file_uploads' settings be enabled and that the remote version of PHP be older than 4.4.3 or 5.1,4.


Upgrade to PmWiki version 2.1.21 or later.
