A security vulnerability has been detected in Edimax EW-7438RPn 1.31. Affected is the function formRadius of the file /goform/formRadius. The manipulation of the argument submit-url leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
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-2026-9461 represents a critical stack-based buffer overflow vulnerability in Edimax EW-7438RPn wireless routers running firmware version 1.31. The vulnerability exists in the formRadius function accessible via the /goform/formRadius endpoint, where insufficient input validation on the submit-url parameter allows attackers to overflow stack memory. This is particularly concerning because Edimax routers are widely deployed in small office and home office (SOHO) environments, making them attractive targets for botnet recruitment and network compromise. The remote exploitability, combined with public disclosure and vendor non-responsiveness, creates an immediate and persistent threat to any organization or individual running affected firmware versions.
Casky's 255 matched security skills leverage Claude's extended reasoning to detect the exploitation patterns associated with this vulnerability across MITRE ATT&CK Execution (TA0002) and Persistence (TA0003) techniques. Practitioners using Casky would identify attack indicators including malformed HTTP requests to /goform/formRadius with oversized submit-url parameters, suspicious process execution following successful buffer overflow (shellcode execution), and lateral movement attempts originating from compromised router devices. The platform's CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-121 (Stack-based Buffer Overflow) focused skills would flag payloads attempting to overwrite stack return addresses, while behavioral analysis skills detect post-exploitation persistence mechanisms such as firmware modifications or scheduled task creation that adversaries commonly establish after gaining code execution on network infrastructure.
