Title: F5 Networks FirePass 4100 SSL VPN My.Logon.PHP3 Cross-Site Scripting Vulnerability

Severity: MODERATE


FirePass 4100 SSL VPN is a secure Virtual Private Network device that uses SSL connections to encapsulate network traffic.

FirePass 4100 SSL VPN devices are prone to a cross-site scripting vulnerability because they fail to properly sanitize user-supplied input.

Specifically, this issue affects the 'my.logon.php3' script.

An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker to steal cookie-based authentication credentials and to launch other attacks.

5.4.1 through 5.5.2

Affected Products:

  • F5 FirePass
