Summary

CVE-2025-49141 is a high-severity OS Command Injection (CWE-78) vulnerability in Psu Haxcms-Nodejs. Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 28% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

HAX CMS PHP, a tool for managing microsites via a PHP backend, is affected by an OS command injection vulnerability (CWE-78) in versions prior to 11.0.3. The flaw resides in the gitImportSite functionality, which takes a URL string from a POST request and performs insufficient validation before the set_remote function passes the input to proc_open for execution.

An authenticated attacker with low-privileged access can supply a crafted URL that evades the filter_var and strpos checks, resulting in arbitrary operating system command execution on the backend server. Command output can then be exfiltrated over HTTP, and the CVSS 8.5 score reflects the high impact on confidentiality, integrity, and availability under a network attack vector with some attack complexity.

The referenced GitHub Security Advisory GHSA-g4cf-pp4x-hqgw and associated commit describe the issue and confirm that version 11.0.3 contains a patch addressing the input validation weakness. The EPSS score has remained flat at 0.0403 with no material increase observed since disclosure.

Vulnerability Data

HAX CMS PHP allows users to manage their microsite universe with a PHP backend. Prior to version 11.0.3, the `gitImportSite` functionality obtains a URL string from a POST request and insufficiently validates user input. The `set_remote` function later passes this…

input into `proc_open`, yielding OS command injection. An authenticated attacker can craft a URL string that bypasses the validation checks employed by the `filter_var` and `strpos` functions in order to execute arbitrary OS commands on the backend server. The attacker can exfiltrate command output via an HTTP request. Version 11.0.3 contains a patch for the issue.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
