CVE-2026-9345 Details
Description
A vulnerability was detected in Edimax EW-7438RPn up to 1.31. This affects the function formWizSurvey of the file /goform/formWizSurvey of the component webs. Performing a manipulation of the argument ssid/manualssid/ip/mask/gateway results in buffer overflow. The attack is possible to be carried out 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 overflow vulnerability has been identified in the Edimax EW-7438RPn Wi-Fi extender, affecting versions through 1.31. The issue arises in the 'formWizSurvey' function of the 'webs' component, where user-supplied arguments such as 'ssid', 'manualssid', 'ip', 'mask', and 'gateway' are not properly validated. This lack of input sanitization allows remote attackers to manipulate these fields, leading to a buffer overflow by overwriting the return address on the stack. The vulnerability can be exploited remotely, causing the device to crash and disrupt normal service.
