CVE-2023-26049

Eclipse Jetty's cookie parsing of quoted values can exfiltrate values from other cookies

Impact

Nonstandard cookie parsing in Jetty 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. So, 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. ### Impact This has security implications because if, say, `JSESSIONID` is an `HttpOnly` cookie, and the `DISPLAY_LANGUAGE` cookie value is rendered on the page, an attacker can smuggle the `JSESSIONID` cookie into the `DISPLAY_LANGUAGE` cookie and thereby exfiltrate it. This is significant when an intermediary is enacting some policy based on cookies, so a smuggled cookie can bypass that policy yet still be seen by the Jetty server. ### Patches * 9.4.51.v20230217 - via PR #9352 * 10.0.15 - via PR #9339 * 11.0.15 - via PR #9339 ### Workarounds No workarounds ### References * https://www.rfc-editor.org/rfc/rfc2965 * https://www.rfc-editor.org/rfc/rfc6265
