Summary

CVE-2026-10061 is a low-severity Injection (CWE-74) vulnerability in Trendnet Tew-432Brp 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 8% 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-432BRP router running firmware 3.10B20. The flaw resides in the formWPS function within /goform/formWPS, where unsanitized input to the peerPin argument allows arbitrary command execution. The issue is tracked as CWE-74 and CWE-77 and received a CVSS 4.0 score of 2.1.

An authenticated attacker with network access can supply a crafted peerPin value to the web interface and execute operating-system commands on the device. Public exploit code is available, enabling remote code execution without user interaction beyond valid credentials.

The vendor has stated that the TEW-432BRP reached end-of-life in 2009 and will not receive patches or further support. No mitigation guidance beyond this declaration appears in the referenced advisories.

EPSS for the CVE rose from a low baseline to a recorded peak of 0.0106, indicating increased exploitation interest after disclosure.

Mitigating Controls (NIST 800-53 r5) AI

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

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

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