Mortbay Jetty 6.1.5 and 6.1.6 allows remote attackers to bypass protection mechanisms and read the source of files via multiple '/' (slash) characters in the URI.

Mortbay Jetty before 6.1.6rc1 does not properly handle "certain quote sequences" in HTML cookie parameters, which allows remote attackers to hijack browser sessions via unspecified vectors.

Cross-site scripting (XSS) vulnerability in Dump Servlet in Mortbay Jetty before 6.1.6rc1 allows remote attackers to inject arbitrary web script or HTML via unspecified parameters and cookies.

Jetty before 4.2.27, 5.1 before 5.1.12, 6.0 before 6.0.2, and 6.1 before 6.1.0pre3 generates predictable session identifiers using java.util.random, which makes it easier for remote attackers to guess a session identifier through brute force attacks, bypass authentication requirements, and possibly conduct cross-site request forgery attacks.
