Authenticated command injection via wireless POST parameters
Published May 23, 2026 · Updated May 23, 2026
Command injection in Edimax BR-6428nS 1.10 allows remote authenticated users to execute arbitrary commands via a crafted POST request. The /goform/formWlanM POST handler passes attacker-controlled wireless-test parameters into system without neutralizing shell metacharacters. Low-privilege access to the router web interface is required, and successful exploitation runs commands in the appliance firmware context.
