view advisory published 2024-10-14Licence: CC-BY-4.0

### 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](https://jetty.org/docs/jetty/12/programming-guide/server/session.html), so that sessions are not stored in memory, but rather in a database or file system that may have significantly more capacity than memory. ### References * https://github.com/jetty/jetty.project/pull/10756 * https://github.com/jetty/jetty.project/pull/10755
