Remote code execution via identical default credentials
Published Sep 12, 2025 · Updated Sep 12, 2025
Hard-coded credentials in H3C Magic M device firmware M2V100R006 allow remote attackers to execute arbitrary code over the network. The firmware stores MD5-crypt hashes for root, useradmin, telecomadmin, and nobody in world-readable /etc/shadow, and each password matches its username. Network access to an exposed administrative interface or service is required; the disclosed root credentials grant full device control.
