Summary

CVE-2025-5606 is a medium-severity Injection (CWE-74) vulnerability in Tenda Ac18 Firmware. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 12% 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.

Deeper analysis AI-assisted summary

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

A vulnerability has been identified in the Tenda AC18 router running firmware version 15.03.05.05. The issue resides in the formSetIptv function within the /goform/SetIPTVCfg endpoint, where improper handling of the list argument enables command injection. The flaw is tracked under CVE-2025-5606, carries a CVSS v4 score of 5.3, and is associated with CWE-74 and CWE-77.

An authenticated attacker with network access can supply a crafted list parameter to the affected endpoint, resulting in arbitrary command execution on the device. Because the attack is remote and requires only low privileges without user interaction, an adversary who has obtained valid credentials or session access can leverage the flaw to run operating-system commands.

Public references include a detailed disclosure on a Notion page along with entries on VulDB that reproduce the injection vector, while the vendor site at tenda.com.cn provides no specific mitigation guidance in the available references. The EPSS score remains flat at 0.0812 with no observed increase after publication.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 Information Input Validation good match

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles include proper neutralization and safe command construction practices.

A.8.28 Secure coding mostly match
prevents

Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches injection vulnerabilities before release.

A.8.15 Logging partial match
finds

Logging supports detection of injection attempts but does not prevent the weakness.

A.8.16 Monitoring activities partial match
finds

Monitoring activities can identify active injection attacks after they occur.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and output encoding that directly prevent injection flaws.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against injection attacks in software design.
