What is the CVSS score of CVE-2025-50857?

CVE-2025-50857 has a CVSS 3.1 base score of 9.8 (Critical). CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. EPSS exploitation probability: 0.8%.

How to fix or mitigate CVE-2025-50857?

Within 24 hours: Identify all ZenTaoPMS instances in your environment and document their versions; implement immediate network access controls to restrict external access to the /module/ai/control.php endpoint. Within 7 days: Apply available security patches if your version is outside the vulnerable range (pre-18.11 or post-21.6.beta); if no patch is available for your version, evaluate upgrading to the latest stable release or implement WAF rules to block file uploads to the AI module. Within 30 days: Complete migration to a patched version, conduct forensic analysis of access logs for indicators of exploitation, and reset all credentials for accounts that may have been compromised.

DescriptionCVE.org

ZenTaoPMS v18.11 through v21.6.beta is vulnerable to Directory Traversal in /module/ai/control.php. This allows attackers to execute arbitrary code via a crafted file upload

Executive ViewAI

Why It Matters

ZenTaoPMS versions 18.11 through 21.6.beta contain a critical remote code execution vulnerability that allows unauthenticated attackers to upload and execute arbitrary code on affected systems. Any organization running vulnerable versions of this project management platform faces immediate risk of complete system compromise, data theft, and operational disruption.

Business Impact: Severe

Compensating Controls

Implement WAF rules to block POST requests to /module/ai/control.php; disable the AI module feature if not actively required; restrict network access to ZenTaoPMS to authorized users only via VPN or IP allowlisting; enable and monitor detailed application and file system logging for suspicious upload activity; consider network segmentation to isolate the ZenTaoPMS instance from critical infrastructure.
