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: 3


The remote webmail application is affected by a cross-site scripting vulnerability.


The installed version of SquirrelMail fails to sanitize user-supplied input before using it in the 'contrib/decrypt_headers.php' script to dynamically generate HTML.

An unauthenticated attacker can exploit this issue to launch cross-site scripting attacks against the affected application.

There are also reportedly several other issues, including cross-site scripting vulnerabilities, a code injection vulnerability, and a session fixation vulnerability, though Nessus has not tested for these.


Upgrade to SquirrelMail 1.4.18 or later.
