CVE-2022-2070 1 Grandstream 2 Gds3710, Gds3710 Firmware 2022-09-26 N/A 9.8 CRITICAL
In Grandstream GSD3710 in its 1.0.11.13 version, it's possible to overflow the stack since it doesn't check the param length before using the sscanf instruction. Because of that, an attacker could create a socket and connect with a remote IP:port by opening a shell and getting full access to the system. The exploit affects daemons dbmng and logsrv that are running on ports 8000 and 8001 by default.
CVE-2022-2025 1 Grandstream 2 Gds3710, Gds3710 Firmware 2022-09-26 N/A 9.8 CRITICAL
an attacker with knowledge of user/pass of Grandstream GSD3710 in its 1.0.11.13 version, could overflow the stack since it doesn't check the param length before use the strcopy instruction. The explotation of this vulnerability may lead an attacker to execute a shell with full access.
CVE-2019-10655 1 Grandstream 10 Gac2500, Gac2500 Firmware, Gvc3202 and 7 more 2022-04-18 7.5 HIGH 9.8 CRITICAL

This can be exploited remotely or via CSRF because the cookie can be placed in an Accept HTTP header in an XMLHttpRequest call to lighttpd.
CVE-2021-37748 1 Grandstream 2 Ht801, Ht801 Firmware 2021-11-03 9.0 HIGH 8.8 HIGH
Multiple buffer overflows in the limited configuration shell (/sbin/gs_config) on Grandstream HT801 devices before 1.0.29 allow remote authenticated users to execute arbitrary code as root via a crafted manage_if setting, thus bypassing the intended restrictions of this shell and taking full control of the device. There are default weak credentials that can be used to authenticate.
