CVE-2021-37748 describes multiple buffer overflows in the /sbin/gs_config shell of Grandstream HT801 devices prior to firmware version 1.0.29. This vulnerability allows remote authenticated attackers, potentially using default weak credentials, to execute arbitrary code as root by manipulating the manage_if setting, thereby gaining full control of the device. With a CVSS score of 8.8 (High), it represents a significant risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
