IBM WebSphere Application Server FAULTACTOR cross-site scripting

websphere-faultactor-xss (30055) The risk level is classified as MediumMedium Risk

Description:

IBM WebSphere Application Server is vulnerable to cross-site scripting, caused by improper validation of user-supplied input passed to the 500 Internal Server Error page on SOAP port 8880. A remote attacker could exploit this vulnerability using the FAULTACTOR element 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.
