Vendor:
The Apache Software Foundation
Versions Affected:
Tomcat 4.1.0 to 4.1.37
Tomcat 5.5.0 to 5.5.26
Tomcat 6.0.0 to 6.0.16
The unsupported Tomcat 3.x, 4.0.x and 5.0.x versions may be also affected
Description:
The message argument of HttpServletResponse.sendError() call is not only
displayed on the error page, but is also used for the reason-phrase of HTTP
response. This may include characters that are illegal in HTTP headers. It
is possible for a specially crafted message to result in arbitrary content
being injected into the HTTP response. For a successful XSS attack,
unfiltered user supplied data must be included in the message argument.
Mitigation:
6.0.x users should upgrade to 6.0.18
5.5.x users should obtain the latest source from svn or apply this patch
which will be included from 5.5.27

which will be included from 4.1.38
