In affected versions envoy incorrectly handled a URI \u0027#fragment\u0027 element as part of the path element. Envoy is configured with an RBAC filter for authorization or similar mechanism with an explicit case of a final \"/admin\" path element, or is using a negative assertion with final path element of \"/admin\". The client sends request to \"/app1/admin#foo\". In Envoy prior to 1.18.0, or 1.18.0+ configured with path_normalization=false. Envoy treats fragment as a suffix of the query string when present, or as a suffix of the path when query string is absent, so it evaluates the final path element as \"/admin#foo\" and mismatches with the configured \"/admin\" path element. In Envoy 1.18.0+ configured with path_normalization=true. Envoy transforms this to /app1/admin%23foo and mismatches with the configured /admin prefix. The resulting URI is sent to the next server-agent with the offending \"#foo\" fragment which violates RFC3986 or with the nonsensical \"%23foo\" text appended. A specifically constructed request with URI containing \u0027#fragment\u0027 element delivered by an untrusted client in the presence of path based request authorization resulting in escalation of Privileges when path based request authorization extensions. Envoy versions 1.19.1, 1.18.4, 1.17.4, 1.16.5 contain fixes that removes fragment from URI path in incoming requests."

In affected versions envoy incorrectly handled a URI \u0027#fragment\u0027 element as part of the path element. Envoy is configured with an RBAC filter for authorization or similar mechanism with an explicit case of a final \"/admin\" path element, or is using a negative assertion with final path element of \"/admin\". The client sends request to \"/app1/admin#foo\". In Envoy prior to 1.18.0, or 1.18.0+ configured with path_normalization=false. Envoy treats fragment as a suffix of the query string when present, or as a suffix of the path when query string is absent, so it evaluates the final path element as \"/admin#foo\" and mismatches with the configured \"/admin\" path element. In Envoy 1.18.0+ configured with path_normalization=true. Envoy transforms this to /app1/admin%23foo and mismatches with the configured /admin prefix. The resulting URI is sent to the next server-agent with the offending \"#foo\" fragment which violates RFC3986 or with the nonsensical \"%23foo\" text appended. A specifically constructed request with URI containing \u0027#fragment\u0027 element delivered by an untrusted client in the presence of path based request authorization resulting in escalation of Privileges when path based request authorization extensions. Envoy versions 1.19.1, 1.18.4, 1.17.4, 1.16.5 contain fixes that removes fragment from URI path in incoming requests."

In affected versions after Envoy sends a locally generated response it must stop further processing of request or response data. However when local response is generated due the internal buffer overflow while request or response is processed by the filter chain the operation may not be stopped completely and result in accessing a freed memory block. A specifically constructed request delivered by an untrusted downstream or upstream peer in the presence of extensions that modify and increase the size of request or response bodies resulting in a Denial of Service when using extensions that modify and increase the size of request or response bodies, such as decompressor filter. Envoy versions 1.19.1, 1.18.4, 1.17.4, 1.16.5 contain fixes to address incomplete termination of request processing after locally generated response. As a workaround disable Envoy\u0027s decompressor, json-transcoder or grpc-web extensions or proprietary extensions that modify and increase the size of request or response bodies, if feasible."
