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

CVE-2025-51958 is a critical vulnerability in the aelsantex runcommand plugin version 2014-04-01 for DokuWiki, enabling unauthenticated attackers to execute arbitrary system commands. The flaw resides in the lib/plugins/runcommand/postaction.php file and is classified as CWE-78 (OS Command Injection). It received 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), indicating high severity due to its potential for remote exploitation without privileges or user interaction.

Any unauthenticated attacker with network access to a vulnerable DokuWiki instance running this plugin can exploit the issue remotely. Exploitation involves sending crafted requests to the postaction.php endpoint, resulting in arbitrary command execution on the underlying server with the privileges of the web server process. This grants attackers high-impact control over confidentiality, integrity, and availability, potentially leading to full system compromise.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

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

SI-10 Information Input Validation good match

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

AC-6 Least Privilege partial match

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

CM-7 Least Functionality partial match

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

SA-8 Security and Privacy Engineering Principles partial match

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

PR.PS-06 mostly match
blocks

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
blocks

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).
