This vulnerability allows local attackers to escalate privileges on affected installations of Cisco Nexus Dashboard Fabric Controller. 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 the configuration of a user permission. A crafted tcpdump command can trigger execution of a privileged operation. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root.
