CVE-2025-24030
Description
A flaw was found in Envoy Gateway. This vulnerability allows a user with access to a Kubernetes cluster where Envoy Gateway is installed to use a path traversal attack to execute Envoy Admin interface commands on proxies managed by Envoy Gateway. The admin interface can terminate the Envoy process and extract the Envoy configuration, possibly containing confidential data.
Statement
This vulnerability marked as Important rather than Moderate due to its potential to compromise the core functionality and security of the Envoy Gateway. The path traversal exploit enables attackers within the Kubernetes cluster to access the Envoy Admin interface, which is highly privileged and designed for debugging and operational control. By exploiting this flaw, attackers can terminate critical processes or retrieve sensitive configuration data, such as API keys, secrets, or routing rules, directly impacting the confidentiality, integrity, and availability of the system.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
