phpMyFAQ before v4.1.6 writes content backup ZIP archives to the web-accessible document root at content.zip, exposing sensitive files including database credentials. Unauthenticated attackers can race concurrent requests to download the temporary ZIP file before deletion, or exploit XSS in admin contexts to trigger authenticated backups and retrieve the archive.
AnalysisAI
phpMyFAQ before v4.1.6 exposes database credentials by writing backup ZIP archives to the publicly accessible document root at a predictable path (content.zip), enabling credential theft via two distinct attack chains. Unauthenticated attackers can race concurrent HTTP requests against the brief window between archive creation and deletion, while a second path chains a stored XSS in the admin panel to force an authenticated backup and retrieve the resulting archive. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The primary unauthenticated race condition path requires that a backup operation is actively in progress on the target phpMyFAQ instance - `content.zip` only exists during the brief interval between file creation and programmatic deletion, meaning the attacker must either poll the path continuously or have foreknowledge of backup timing. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.0 accurately reflects substantive exploitation constraints: AC:H and AT:P together acknowledge that the primary unauthenticated race condition requires the backup to be actively in progress - a narrow window that makes opportunistic mass exploitation impractical without persistent polling. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker discovers a phpMyFAQ instance prior to v4.1.6 and initiates a loop of HTTP GET requests to `https://target.example.com/content.zip`, polling repeatedly or triggering concurrent requests designed to intersect with any scheduled or admin-initiated backup. When an administrator runs a backup, the attacker's polling request succeeds during the creation-to-deletion window and downloads the credential archive. … |
| Remediation | Upgrade phpMyFAQ to version 4.1.6 or later, which is confirmed as the vendor-released patch per the GitHub Security Advisory GHSA-8hmh-mrx6-pqvf at https://github.com/thorsten/phpMyFAQ/security/advisories/GHSA-8hmh-mrx6-pqvf. … Detailed patch versions, workarounds, and compensating controls in full report. |
