CVE-2024-7079
Description
A flaw was found in the Openshift console. The /API/helm/verify endpoint is tasked to fetch and verify the installation of a Helm chart from a URI that is remote HTTP/HTTPS or local. Access to this endpoint is gated by the authHandlerWithUser() middleware function. Contrary to its name, this middleware function does not verify the validity of the user's credentials. As a result, unauthenticated users can access this endpoint.
Statement
This vulnerability is considered moderate rather than important because it does not lead to privilege escalation or direct compromise of the cluster. The impact is constrained to the scope of the openshift-console:console service account, which has limited privileges and does not provide administrative-level access. While the vulnerability does allow for unauthorized HTTP/HTTPS requests and could lead to denial-of-service conditions within the console, it does not allow attackers to manipulate cluster resources beyond what the console can already access.
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.

Understanding the Weakness (CWE)
Access Control,Other
Technical Impact: Gain Privileges or Assume Identity; Varies by Context
Exposing critical functionality essentially provides an attacker with the privilege level of that functionality. The consequences will depend on the associated functionality, but they can range from reading or modifying sensitive data, accessing administrative or other privileged functionality, or possibly even executing arbitrary code.
