Authenticated memory corruption via unchecked key copy
Published May 24, 2026 · Updated May 24, 2026
Stack buffer overflow in Edimax EW-7438RPn 1.28a allows remote authenticated users to corrupt memory via a crafted key1 value. The formwlencrypt24g POST handler passes the attacker-controlled value to strcpy, which copies it into a fixed-size stack buffer without a length check. Access to the network-local administration interface is required; successful exploitation can crash the device or execute code in the handler's context.
