Buffer not correctly recycled in Gzip Request inflation
Impact
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
CVE score is 4.8 AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:L
Workarounds
The problem can be worked around by either:
- Disabling compressed request body inflation by GzipHandler.
- By always fully consuming the request content before sending a response.
- By adding a
Connection: closeto any response where the servlet does not fully consume request content.
