A vulnerability has been found in TRENDnet TEW-432BRP 3.10B20. This affects the function formSetProtocolFilter of the file /goform/formSetProtocolFilter. Such manipulation of the argument protocol_name leads to stack-based buffer overflow. The attack may be performed from remote. The exploit has been disclosed to the public and may be used. The vendor explains: "This product has been EOL for 15 years (since 2009). As the item has been EOL for such a long time, we are not able to replicate or fix any vulnerabilities." This vulnerability only affects products that are no longer supported by the maintainer.
Casky was already ahead
This CVE exploits attack patterns that Casky's 255matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.
CVE-2026-10122 represents a critical stack-based buffer overflow vulnerability in the TRENDnet TEW-432BRP router's protocol filter functionality, affecting the formSetProtocolFilter function through improper handling of the protocol_name argument. While this device reached end-of-life in 2009, it remains deployed in legacy networks where it represents a significant attack surface. Remote attackers can exploit this vulnerability without authentication to achieve arbitrary code execution, making it particularly dangerous for organizations still relying on aging network infrastructure. The 8.8 CVSS score reflects the combination of network accessibility, low complexity, and high impact on confidentiality, integrity, and availability.
Casky.ai's 255 mapped security skills leverage Claude's extended reasoning to detect exploitation attempts targeting this vulnerability by correlating indicators across MITRE ATT&CK techniques TA0002 (Execution) and TA0003 (Persistence). Practitioners using Casky would identify suspicious patterns including malformed HTTP requests to the /goform/formSetProtocolFilter endpoint with oversized protocol_name parameters, abnormal process behavior following successful buffer overflow (process crashes, unexpected child process spawning), and network traffic anomalies indicating command injection or reverse shell establishment. The platform's skill mapping enables detection of both initial exploitation attempts and post-compromise lateral movement, allowing security teams to correlate buffer overflow exploitation with persistence mechanisms commonly chained after code execution on compromised routers.
