Title
Grandstream GXP1625 Network Status api.values.post cross site scripting
Summary
A security flaw has been discovered in Grandstream GXP1625 1.0.7.4. The impacted element is an unknown function of the file /cgi-bin/api.values.post of the component Network Status Page. Performing manipulation of the argument vpn_ip results in basic cross site scripting. Remote exploitation of the attack is possible. The exploit has been released to the public and may be exploited. The vendor was contacted early about this disclosure but did not respond in any way.

Title
Grandstream GSD3710 Stack-based Buffer Overflow
Summary
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.
Severity
