CVE-2022-20926Network attack vector

Authenticated command execution via insufficient API validation

Published Nov 10, 2022 · Updated Oct 25, 2024

Command injection in Cisco Firepower Management Center 7.0.0 through 7.1.0.2 allows remote authenticated users to execute OS commands. Certain web management API endpoints pass insufficiently validated user-supplied parameters into operating-system commands. Exploitation requires Device permissions, assigned by default only to Administrator, Security Approver, and Network Admin roles, and commands run with low system privileges.
