Headline
GHSA-r7m4-f9h5-gr79: Eclipse Jetty's PushSessionCacheFilter can cause remote DoS attacks
Impact
Jetty PushSessionCacheFilter can be exploited by unauthenticated users to launch remote DoS attacks by exhausting the server’s memory.
Patches
- https://github.com/jetty/jetty.project/pull/9715
- https://github.com/jetty/jetty.project/pull/9716
Workarounds
The session usage is intrinsic to the design of the PushCacheFilter. The issue can be avoided by:
- not using the PushCacheFilter. Push has been deprecated by the various IETF specs and early hints responses should be used instead.
- reducing the reducing the idle timeout on unauthenticated sessions will reduce the time such session stay in memory.
- configuring a session cache to use session passivation, so that sessions are not stored in memory, but rather in a database or file system that may have significantly more capacity than memory.
