Summary

CVE-2026-5183 is a low-severity Injection (CWE-74) vulnerability in Trendnet Tew-713Re Firmware. Its CVSS base score is 2.1 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Dynamic Linker Hijacking (T1574.006); ranked in the top 5% 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 command injection vulnerability exists in the TRENDnet TEW-713RE wireless range extender up to firmware version 1.02. The flaw resides in the sub_421494 function within /goform/addRouting, where unsanitized input to the dest argument is passed to an operating system command. The issue is tracked under CWE-74 and CWE-77 and carries a CVSS 4.0 score of 2.1.

An authenticated remote attacker can supply a crafted dest value to execute arbitrary commands on the device. The attack requires no user interaction and can be launched over the network; a public proof-of-concept has already been released.

No vendor patch or advisory has been issued. The manufacturer was notified prior to disclosure but did not respond. The EPSS score rose from a low baseline to a recorded peak of 0.0141, indicating measurable post-disclosure exploitation interest that warrants renewed monitoring.

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.8.15 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.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles reduce injection surfaces but do not prescribe specific neutralization techniques.

A.8.28 Secure coding partial match
prevents

Secure coding standards require proper neutralization of special elements, directly addressing CWE-74.
