Summary
Eclipse Jetty's PushSessionCacheFilter can cause remote DoS attacks
Details

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.
