Name of the Vulnerable Software and Affected Versions Edimax EW-7438RPn version 1.31

Description A stack-based buffer overflow can be triggered remotely via the /goform/formAccept endpoint. The issue exists within the formAccept() function when processing the submit-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 At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the /goform/formAccept endpoint to minimize the risk of exploitation.
