The vulnerability of the decode/encodeBody component in the Envoy proxy server allows a attacker to induce a service failure.

The vulnerability of the decode/encodeBody component in the Envoy proxy server is related to an uncontrolled resource consumption. Exploiting this vulnerability could allow a malicious actor to cause service interruptions by uploading a specially created zip file...

CVE-2022-31045

A flaw was found in Istio. Memory access violation of ill-formed headers sent to Envoy in certain configurations can lead to unexpected memory access, resulting in undefined behavior or crashing...

CVE-2022-29228

A flaw was found in Envoy. The OAuth filter would try to invoke the remaining filters in the chain after emitting a local response, which triggers an ASSERT in newer versions and corrupts memory on earlier versions...

CVE-2022-29226

A flaw was found in Envoy. The OAuth filter does not include an implementation for validating access tokens, allowing remote attackers to bypass authentication to Envoy by providing any token value. Mitigation There is no known mitigation for this flaw...

Denial Of Service (DoS)

Envoy is vulnerable to denial of service. The vulnerability exists due to a segmentation fault in the GrpcHealthCheckerImpl allowing an attacker to crash the system by controlling an upstream host and also controlling the service discovery of that host via DNS, the EDS API, etc. and forcing the...
