Description
phpMyFAQ before 4.1.2 contains an insufficient authorization vulnerability in admin-api routes that allows authenticated ordinary users to access administrative endpoints by only checking login status instead of verifying backend privileges. Attackers with valid frontend user accounts can access sensitive backend operational information including dashboard versions, LDAP configuration, Elasticsearch statistics, and health-check data.

AI Analysis

Impact

A flaw in phpMyFAQ allows authenticated users with ordinary accounts to reach administrative API endpoints because the system only verifies that the user is logged in, not that they possess administrator privileges (CWE‑863). By requesting these endpoints, an attacker can obtain vulnerable administrative information such as dashboard versions, LDAP configuration details, Elasticsearch statistics, and health‑check data.

Affected Systems

The vulnerability affects installations of phpMyFAQ older than version 4.1.2. Users running these releases should be aware of the issue.

Risk and Exploitability

The CVSS score of 5.3 indicates a moderate to high severity. The EPSS score is <1%, showing a very low but non‑zero likelihood of exploitation, and the vulnerability is not listed in CISA’s KEV catalog. Exploitation requires the attacker to hold a valid authenticated frontend account; after logging in, the attacker can send requests to the protected admin API endpoints and retrieve sensitive information. No remote code execution or denial‑of‑service impact is disclosed.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade phpMyFAQ to version 4.1.2 or later to remove the missing authorization check.
  • Ensure that user accounts have appropriate role assignments and that administrative APIs are protected by comprehensive access controls.
  • Audit logs to detect unusual API usage patterns by ordinary users, and implement monitoring or alerting for such activity.
