Description
CamaleonCMS version 2.9.2 and earlier contains a missing authorization vulnerability in the admin users controller that allows any authenticated user to access any other user's profile data by supplying an arbitrary user ID parameter. Attackers can send a GET request to the admin profile endpoint with an enumerable sequential integer user ID to disclose profile information of any user, including administrators, due to the profile action being excluded from the role validation filter with no compensating ownership check.

AI Analysis

Impact

The vulnerability is a missing authorization flaw in the admin users controller that lets any authenticated user read another user's profile by supplying a numeric ID. Attackers can issue a GET request to the admin profile endpoint with an arbitrary sequential user ID and retrieve profile information of any user, including administrators, because the profile action bypasses role validation and has no ownership check.

Affected Systems

CamaleonCMS version 2.9.2 and all earlier releases, released by the vendor owen2345, are affected. Users running these versions should verify the patch state of their installation.

Risk and Exploitability

The CVSS score of 5.3 indicates a moderate confidentiality impact, while the EPSS score of <1% reflects a low likelihood of exploitation at this time. The vulnerability is not listed in the CISA KEV catalog, and it does not provide code execution or denial‑of‑service capabilities. The attack vector is inferred to be remote via authenticated HTTP requests; an attacker only needs legitimate credentials to enumerate and read any profile.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade CamaleonCMS to the latest released version that includes the authorization fix.
  • If an upgrade is not immediately possible, apply the patch commit ae10da7cfce902a8552927c57b0a562fb1676040 from the project's repository to restore role validation on the profile action.
  • As a temporary workaround, restrict access to the /admin/profile endpoint to users with the administrator role or use a firewall rule to block unauthenticated access to that URL.
