Summary

CVE-2024-12828 is a high-severity OS Command Injection (CWE-78) vulnerability in Webmin Webmin. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

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.

Deeper analysis AI-assisted summary

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

CVE-2024-12828 is a command injection vulnerability in Webmin that permits remote code execution. The flaw lies in the handling of CGI requests, where a user-supplied string is used in a system call without adequate validation, and it is tracked under CWE-78. Affected installations allow an authenticated attacker to run arbitrary commands.

An attacker who has already authenticated to Webmin can supply a crafted string via CGI handling to achieve code execution in the context of the root user. The vulnerability carries a CVSS 3.1 score of 8.8 with network attack vector, low complexity, and no user interaction required.

A patch addressing the issue appears in the authentic-theme repository, referenced by commit 61e5b10227b50407e3c6ac494ffbd4385d1b59df, and further details are available in ZDI-24-1725. The EPSS score has remained flat at its peak value of 0.2172 with no material increase observed after disclosure.

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 mostly match

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
prevents

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).
