A vulnerability in the command-line tcpdump utility in the Cisco SD-WAN Solution could allow an authenticated, local attacker to inject arbitrary commands that are executed with root privileges. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by authenticating to the device and submitting crafted input to the tcpdump utility. The attacker must be authenticated to access the tcpdump utility. A successful exploit could allow the attacker to execute…
In Dell EMC Isilon OneFS, the compadmin is able to run tcpdump binary with root privileges. In versions between 8.1.0.0 - 8.1.0.1, 8.0.1.0 - 8.0.1.2, and 8.0.0.0 - 8.0.0.6, the tcpdump binary, being run with sudo, may potentially be used by compadmin to execute arbitrary code with root privileges.
