Published: 31 March 2026
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.
