CVE-2026-9346 Details
Description
A flaw has been found in Edimax EW-7438RPn up to 1.31. This impacts the function formWirelessTbl of the file /goform/formWirelessTbl of the component webs. Executing a manipulation of the argument submit-url can lead to buffer overflow. The attack may be performed from remote. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A buffer overflow vulnerability has been identified in the Edimax EW-7438RPn range extender, affecting versions prior to 1.31. The issue arises in the 'formWirelessTbl' function within the 'webs' component, where the 'submit-url' parameter is not properly validated before being copied to a local variable on the stack. This oversight allows remote attackers to manipulate the 'submit-url' argument, leading to a stack overflow that can potentially be exploited to execute arbitrary code. The vulnerability has been publicly disclosed and is available for exploitation.
