Advisory Weakness Curation

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 https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:L&version=3.1 ### 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: close` to any response where the servlet does not fully consume request content.

Buffer not correctly recycled in Gzip Request inflation In Eclipse Jetty 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 but not consumed by the application, then a subsequent request on the same connection will see that body prepended to its body. The attacker will not see any data but may inject data into the body of the subsequent request.

Sensitive Information in Resource Not Removed Before Reuse In Eclipse Jetty RC0 to v20201102 alpha0 to beta2 alpha0 to beta2, 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 but not consumed by the application, then a subsequent request on the same connection will see that body prepended to its body. The attacker will not see any data but may inject data into the body of the subsequent request.
