CVE-2026-9480 Details
Description
A vulnerability was detected in Edimax EW-7438RPn 1.31. The impacted element is the function formrefresh of the file /goform/formrefresh. The manipulation of the argument submit-url results in stack-based buffer overflow. It is possible to launch the attack remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A stack-based buffer overflow vulnerability has been identified in the Edimax EW-7438RPn range extender, specifically in version 1.31. The issue arises in the 'formrefresh' function of the '/goform/formrefresh' file, where the 'submit-url' argument is not properly validated. This lack of input sanitation allows remote attackers to manipulate the 'submit-url' parameter, leading to a buffer overflow by overwriting the function's return address. The vulnerability can be exploited to execute arbitrary code, and the exploit is currently public.
