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 Exploit Public-Facing Application (T1190); ranked in the top 8.7% 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

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.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.008 Network Device CLI Execution
Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.
T1210 Exploitation of Remote Services Lateral Movement
Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.
Why these techniques?

Command injection in the web management interface (/goform/addRouting) of a network device (wireless range extender) enables exploitation of public-facing applications (T1190), exploitation of remote services (T1210), and injection for network device CLI execution (T1059.008).
