Summary

CVE-2025-67164 is a critical-severity OS Command Injection (CWE-78) vulnerability in Pagekit Pagekit. Its CVSS base score is 9.9 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 35.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-3 (Malicious Code Protection).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. 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

Directly mitigates the arbitrary file upload vulnerability by validating uploaded file types, extensions, and content to block crafted PHP files.

SI-3 Malicious Code Protection good match

preventdetect

Scans uploaded files in real-time for malicious code, preventing storage and execution of crafted PHP shells that enable arbitrary code execution.

SI-9 Information Input Restrictions partial match

prevent

Restricts file upload inputs to approved types and formats, limiting the ability to upload executable PHP files even for authenticated users.

NVD Description

An authenticated arbitrary file upload vulnerability in the /storage/poc.php component of Pagekit CMS v1.0.18 allows attackers to execute arbitrary code via uploading a crafted PHP file.

Deeper analysisAI

CVE-2025-67164 is an authenticated arbitrary file upload vulnerability in the /storage/poc.php component of Pagekit CMS version 1.0.18. Published on 2025-12-17, it enables attackers to execute arbitrary code by uploading a crafted PHP file, with associated weakness enumerations including CWE-78, CWE-94, and CWE-434. The vulnerability carries a CVSS v3.1 base score of 9.9, indicating critical severity.

An attacker with low privileges (PR:L), such as an authenticated user, can exploit this remotely (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Exploitation changes scope (S:C) and results in high impacts to confidentiality (C:H), integrity (I:H), and availability (A:H), potentially allowing full remote code execution on the server.

A proof-of-concept exploit is documented in the vulnerability research repository at https://github.com/mbiesiad/vulnerability-research/tree/main/CVE-2025-67164. No official advisories or patch details are specified in the available information.
