Magic B3
Monthly
Remote buffer overflow in H3C Magic B3 routers (firmware up to 100R002) allows attackers with high privileges to corrupt memory via the UpdateWanParams function in /goform/aspForm by manipulating the param argument. Publicly available exploit code exists per VulDB disclosure, though the vendor did not respond to coordinated disclosure attempts. With CVSS 4.0 score of 7.3 and PR:H requirement, exploitation hinges on prior administrative access to the device's web interface.
