DescriptionCVE.org

A vulnerability has been found in Faveo Helpdesk up to 2.0.3. Affected is the function unlink of the file app/Http/Controllers/Admin/helpdesk/SettingsController.php of the component Logo Handler. Such manipulation of the argument data1 leads to path traversal. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Path traversal in Faveo Helpdesk versions 2.0.0 through 2.0.3 enables remote authenticated administrators to delete arbitrary files on the server by manipulating the data1 argument passed to PHP's unlink() function within the Logo Handler component (SettingsController.php). Exploitation is limited to accounts holding high privileges, constraining realistic impact despite network reachability. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated session with high (administrator-level) privileges in Faveo Helpdesk, as confirmed by PR:H in the CVSS 4.0 vector. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 2.0 (Low) accurately reflects the constrained real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained valid admin credentials to a Faveo Helpdesk 2.0.x instance - whether through credential stuffing, phishing, or prior compromise - navigates to the Logo Handler settings page and submits a crafted POST request with a `data1` parameter containing path traversal sequences (e.g., `../../config/database.php`). The application passes this value directly to `unlink()`, deleting the targeted file. …
Remediation No vendor-released patch has been identified at time of analysis; the vendor has not responded to the issue report filed via GitHub (https://github.com/faveosuite/faveo-helpdesk/issues/8343). … Detailed patch versions, workarounds, and compensating controls in full report.
