Barracuda SSL VPN - 'fileSystem.do' Multiple Cross-Site Scripting Vulnerabilities
Barracuda SSL VPN - 'launchAgent.do?return-To' Cross-Site Scripting
source: https://www.securityfocus.com/bid/54593/info
Barracuda SSL VPN 680 is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.
An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks.
Barracuda SSL VPN 680 versions prior to 2.2.2.203 are vulnerable.
