Name of the Vulnerable Software and Affected Versions Edimax EW-7438RPn versions prior to 1.32

Description A stack-based buffer overflow can be executed remotely via the webs component. The issue exists in an unknown function within the '/goform/formWpsStart' endpoint when manipulating the pinCode/wlan-url argument. A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than the buffer is allocated to hold, potentially leading to crashes or arbitrary code execution.

Recommendations Update Edimax EW-7438RPn to version 1.32 or later. As a temporary workaround, restrict access to the '/goform/formWpsStart' endpoint to minimize the risk of exploitation.
