Description


Some vulnerabilities have been reported in Jetty, which can be exploited by malicious people to disclose sensitive information or conduct cross-site scripting attacks.

1) A vulnerability is caused due to an input validation error within the HTTP server when processing HTTP requests. This can be exploited to access files outside of the web application or document tree.

Successful exploitation requires usage of the DefaultServlet with support for aliases enabled or usage of the ResourceHandler class to serve static content. UNIX system are only vulnerable if a directory with a name ending with the character "?" exists in the webapp or docroot.

2) Input passed via the URL is not properly sanitised before being returned to the user when displaying a web directory listing. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerabilities are reported in versions 6.1.16 and prior.


Solution:
Update to version 6.1.17.

Provided and/or discovered by:
1) Greg Wilkins
