The manipulation of the argument submit-url leads to stack-based buffer overflow. It is possible to initiate the attack 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.
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 formLogout function within the file /goform/formLogout, where the submit-url parameter is not properly validated. This lack of input sanitization allows remote attackers to manipulate the submit-url argument, leading to a buffer overflow by overwriting the function's return address. The vulnerability has been publicly disclosed and can be exploited remotely.
