Eclipse Jetty Gzip Vulnerability (Windows)

Eclipse Jetty is prone to a vulnerability where the buffer is not correctly recycled in Gzip Request inflation.

If GZIP request body inflation is enabled and requests from different clients are multiplexed onto a single connection and if an attacker can send a request with a body that is received entirely by not consumed by the application, then a subsequent request on the same connection will see that body prepended to it's body. The attacker will not see any data, but may inject data into the body of the subsequent request.

Eclipse Jetty versions 9.4.0.RC0 - 9.4.34.v20201102, 10.0.0.alpha0 - 10.0.0.beta2 and 11.0.0.alpha0 - 11.0.0.beta2.

Checks if a vulnerable version is present on the target host.

Update to versions 9.4.35.v20201120, 10.0.0.beta3, 11.0.0.beta3 or later.
