CyberRota Analysis
AI-GeneratedEnvoy versions prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1 are vulnerable to a path traversal issue where a remote client can exploit semicolon matrix parameters to bypass access controls, potentially allowing unauthorized access to protected resources. This vulnerability primarily affects deployments using Envoy in conjunction with servlet backends like Apache Tomcat that strip these parameters. Organizations utilizing affected versions of Envoy should prioritize updating to the patched versions to mitigate the risk of unauthorized access.

Original NVD Description
Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy normally matches the raw request path, while servlet backends such as Apache Tomcat strip semicolon matrix parameters from each path segment before resolving the resource. Envoy's ignore_path_parameters_in_path_matching option instead truncates at the first semicolon and still does not match per-segment backend behavior. A remote client can use a parameterized protected segment, or a parameter on an earlier segment, to make Envoy select an unprotected fallback while the backend resolves the protected resource. The relevant scope boundary is that the bypass requires both a path-based Envoy decision and a backend that strips semicolon parameters per segment. This issue is fixed in versions 1.36.10, 1.37.6, 1.38.4, and 1.39.1.
