This vulnerability allows local attackers to escalate privileges on affected installations of Cisco RV340 routers. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within confd_cli. The issue results from executing user commands at an unnecessarily high privilege level. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root.
