CVE-2021-43283
A command injection vulnerability was found within the web interface of the device, allowing an attacker with valid credentials to inject arbitrary shell commands to be executed by the device with root privileges.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.57%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered on Victure WR1200 devices through 1.0.3. A command injection vulnerability was found within the web interface of the device, allowing an attacker with valid credentials to inject arbitrary shell commands to be executed by the device with root privileges. This occurs in the ping and traceroute features. An attacker would thus be able to use this vulnerability to open a reverse shell on the device with root privileges.
