Overview

org.eclipse.jetty:jetty-server is a lightweight highly scalable java based web server and servlet engine.

Affected versions of this package are vulnerable to Information Exposure such that nonstandard cookie parsing may allow an attacker to smuggle cookies within other cookies, or otherwise perform unintended behavior by tampering with the cookie parsing mechanism. If Jetty sees a cookie VALUE that starts with " (double quote), it will continue to read the cookie string until it sees a closing quote -- even if a semicolon is encountered. Exploiting this vulnerability results in cookies exfiltration and policy based on cookies bypass.

Note: A cookie header such as: DISPLAY_LANGUAGE="b; JSESSIONID=1337; c=d" will be parsed as one cookie, with the name DISPLAY_LANGUAGE and a value of b; JSESSIONID=1337; c=d instead of 3 separate cookies.
