CVE-2024-42457Network attack vector

Credential disclosure via attacker-controlled host addition

Published Dec 4, 2024 · Updated Dec 4, 2024

Credential exposure in Veeam Backup & Replication 12.2.0.334 and earlier allows remote authenticated users to read saved credentials. The remote management interface lets an operator enumerate credentials through a session object and misuse host addition with an attacker-controlled IP to receive them in plaintext. A Viewer or Operator role on the backup server is required, and the documented impact is disclosure of stored secrets without integrity or availability loss.
