CVE-2020-37096Public exploitNetwork attack vector

MAC filtering changes via forged cross-origin POST

Published Feb 3, 2026 · Updated Feb 3, 2026

Cross-site request forgery in Edimax EW-7438RPn Mini 1.13 allows context-dependent attackers to add MAC filtering rules. The /goform/formWlAc handler accepts a cross-origin POST containing attacker-supplied MAC-filter parameters without request-forgery protection. A user must visit attacker-controlled content while the device interface is reachable from the browser; the accepted request alters MAC access-control state.
