Citrix Gateway provides an authentication mechanism for remote device access, and Citrix ADC provides load balancing.
Citrix ADC and Gateway are vulnerable to cross-site scripting, caused by improper validation of user-supplied input.
A remote attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
By turning this into a traffic file and matching rule, we are able to detect attempts to steal the victim's cookie-based authentication credentials.
Idappcom has created signature 8023997 along with a traffic file.
