CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to conduct man-in-the-middle attack.

The vulnerability exists in the Zero Touch Provisioning feature of the Cisco SD-WAN Solution due to insufficient certificate validation. A remote attacker can supply a specially crafted certificate, conduct man-in-the-middle attacks and decrypt confidential information on user connections to the affected software.

CWE-ID: CWE-77 - Command injection

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to execute arbitrary commands.

The vulnerability exists in the command-line interface (CLI) in the Cisco SD-WAN Solution due to insufficient input validation. A local attacker can submit specially crafted input to the CLI utility to inject and execute commands with root privileges.


3) Privilege escalation (CVE-ID: CVE-2018-0432)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote authenticated attacker to gain elevated privileges.

The vulnerability exists in the error reporting feature of the Cisco SD-WAN Solution due to improper validation of certain parameters included within the error reporting application configuration. A remote attacker can send a specially crafted command to the error reporting feature, gain root-level privileges and take full control of the device.
