Description: A vulnerability was reported in Struts. A remote user may be able to cause denial of service conditions. A remote user may be able to conduct cross-site scripting attacks. A remote user may be able to bypass a validation process.
A remote user can submit a request with a specially crafted 'org.apache.struts.taglib.html.Constants.CANCEL' parameter. If the target
application does not use the isCancelled() check, the validation process may be bypassed.
When used with BeanUtils 1.7, a remote
user can send a multipart/form-data encoded form with a specially crafted parameter name that references the public getMultipartRequestHandler()
method to cause denial of service conditions on the target application.
The LookupDispatchAction function does not properly filter
HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed
by the target user's browser. The code will originate from the site running the Struts software and will run in the security context
of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any,
associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site
acting as the target user.
