Cross Site Scripting Vulnerability In IBM Websphere
27 February 2005
Nuri Fattah of ProCheckUp Ltd.
WebSphere Application Server is vulnerable to a Cross Site Scripting attack through the Internal Server Error page used on port 8880 of the default WebSphere installation. This may allow the execution of malicious script code in the browser of an individual who clicks on a link to a site using the vulnerable version of WebSphere.
GET /<SCRIPT>alert('Can%20Cross%20Site%20Attack')</SCRIPT> HTTP/1.1
HTTP/1.1 500 Internal Server Error
Server: WebSphere Application Server/6.0

our original advisory contained a typo in the SOAP tag name ('faultfactor' as opossed to 'faultactor'). i.e., "actor" not "factor".
This has been tested on WebSphere Application Server version 6.x. Other versions may be vulnerable but this has not been verified.
