Name of the Vulnerable Software and Affected Versions

For Milesight UR32L version 32.3.0.5, consider disabling the
set l2tp function until a patch is available to prevent exploitation. Restrict access to the vtysh ubus binary to minimize the risk of exploitation. Avoid using the remote subnet and remote mask variables in the affected HTTP requests until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
