Some vulnerabilities have been reported in Jetty, which can be exploited by malicious people to conduct HTTP response splitting and cross-site scripting attacks and potentially hijack a user session.

1) Input passed to unspecified parameters is not properly sanitised before being returned to the user. This can be exploited to insert arbitrary HTTP headers, which will be included in a response to the user.

2) Input passed to unspecified parameters in the Jetty Dump Servlet 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.

3) An error exists in the handling of cookies with certain quote sequences, which can potentially facilitate to hijack a user session.

The vulnerabilities are reported in versions prior to 6.1.6.
