An attacker with a valid backup file and encryption password from an affected device could decrypt the backup file. The attacker could then use the authentication details in the backup file to access internal-only APIs on the affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user."}], "lastModified": "2026-04-03T16:11:11.357", "sourceIdentifier": "psirt@cisco.com"}
