Some vulnerabilities have been reported in IBM WebSphere Application Server, which can be exploited by malicious people to conduct cross-site scripting attacks or bypass certain security restrictions.

1) Input passed via the URL to /ibm/console/ is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

2) An unspecified error can lead to WebSphere Application Server administrative console user sessions being accessible under certain circumstances.

3) An unspecified error can cause the JAX-RPC WS-Security runtime to incorrectly validate a UsernameToken.
