CVE-2021-37748grandstreamht801_firmware
EPSS score7.41%
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.CVE-2021-37915grandstreamht801_firmwareEPSS score2.03%
An issue was discovered on the Grandstream HT801 Analog Telephone Adaptor before 1.0.29.8. From the limited configuration shell, it is possible to set the malicious gdb_debug_server variable. As a result, after a reboot, the device downloads and executes malicious scripts from an attacker-defined host.CVE-2020-5762grandstreamht801_firmware+5EPSS score3.36%
Grandstream HT800 series firmware version 1.0.17.5 and below is vulnerable to a denial of service attack against the TR-069 service. An unauthenticated remote attacker can stop the service due to a NULL pointer dereference in the TR-069 service. This condition is triggered due to mishandling of the HTTP Authentication field.CVE-2020-5760grandstreamht801_firmware+5EPSS score5.47%
Grandstream HT800 series firmware version 1.0.17.5 and below is vulnerable to an OS command injection vulnerability. Unauthenticated remote attackers can execute arbitrary commands as root by crafting a special configuration file and sending a crafted SIP message.CVE-2020-5761grandstreamht801_firmware+5EPSS score4.09%
Grandstream HT800 series firmware version 1.0.17.5 and below is vulnerable to CPU exhaustion due to an infinite loop in the TR-069 service. Unauthenticated remote attackers can trigger this case by sending a one character TCP message to the TR-069 service.CVE-2020-5763grandstreamht801_firmware+5EPSS score2.73%
Grandstream HT800 series firmware version 1.0.17.5 and below contain a backdoor in the SSH service. An authenticated remote attacker can obtain a root shell by correctly answering a challenge prompt.
