Envoy vulnerable to HTTP/2 memory leak in nghttp2 codec

...

The vulnerability of the HTTP CORS filter of the Envoy proxy server allows a perpetrator to execute a DoS attack.

The vulnerability of the HTTP CORS proxy server Envoy’s filter relates to the use of memory after it is freed. Exploiting this vulnerability allows a remote attacker to perform a DoS attack by removing the origin header between the decodeHeaders and encodeHeaders operations...

The vulnerability of the Envoy proxy server stems from a lack of mechanisms for encoding or filtering output data, allowing attackers to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the Envoy proxy server is related to the lack of mechanisms for encoding or filtering output data. Exploiting this vulnerability allows a malicious actor to compromise the confidentiality, integrity, and accessibility of the protected information...

The vulnerability of the Envoy proxy server, related to an incorrect handling after release, allows a attacker to perform a DoS attack.

The vulnerability of the Envoy proxy server is related to an error that occurs after liberation. Exploiting this vulnerability allows a remote attacker to carry out a DoS attack...

The vulnerability of the Envoy proxy server, related to errors in processing mixed-case schemes in HTTP/2, allows attackers to gain access to protected data.

The vulnerability of the Envoy proxy server is related to errors in the processing of mixed-case schemes in HTTP/2. Exploiting this vulnerability can allow a remote attacker to gain access to protected data...

Improper Authorization

github.com/envoyproxy/envoy is vulnerable to Improper Authorization. In rare circumstances, a rogue client is able to create credentials that are always valid. This occurs due to a few uncommon circumstances in which the HMAC payload might always be legitimate in the OAuth2 filter's check...

CVE-2023-35943

A flaw was found in Envoy. Suppose an origin header is configured to be removed with requestheaderstoremove: origin. The CORS filter will segfault and crash Envoy when the origin header is removed and deleted between decodeHeaders and encodeHeaders...

CVE-2023-35942

A flaw was found in Envoy, where gRPC access loggers using the listener's global scope can cause a use-after-free crash when the listener is drained. This issue can be triggered by a listener discovery service LDS update with the same gRPC access log configuration...

CVE-2023-35941

A flaw was found in Envoy, where a malicious client can construct credentials with permanent validity in a specific scenario. This issue is caused by some rare scenarios, such as the combination of host and expiration time, in which the HMAC payload can always be valid in the OAuth2 filter's HMAC...

CVE-2023-35944

A flaw was found in Envoy that allows for mixed-case schemes in HTTP/2. However, some internal scheme checks in Envoy are case-sensitive, leading to incorrect handling of requests and responses with mixed case schemes. For example, if a request with a mixed scheme HTTP is sent to the OAuth2 filte...
