Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Requires validation of user-supplied inputs like file paths, directly preventing directory traversal in the crafted file upload to /module/ai/control.php.

SI-2 Flaw Remediation good match

prevent

Mandates timely identification, reporting, and correction of flaws, directly remediating the directory traversal vulnerability leading to arbitrary code execution.

SC-7 Boundary Protection partial match

prevent

Boundary protection with web application firewalls can inspect and block network requests containing directory traversal sequences in file uploads.

NVD Description

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

Deeper analysisAI

ZenTaoPMS versions v18.11 through v21.6.beta are affected by CVE-2025-50857, a directory traversal vulnerability (CWE-22) in the /module/ai/control.php component. This flaw allows attackers to execute arbitrary code through a crafted file upload.

The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical. Unauthenticated remote attackers can exploit it over the network with low attack complexity and no user interaction required, achieving high-impact arbitrary code execution that compromises confidentiality, integrity, and availability.
