CVE-2024-42457: Veeam Backup & Replication

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

A vulnerability in Veeam Backup & Replication allows users with certain operator roles to expose saved credentials by leveraging a combination of methods in a remote management interface. This can be achieved using a session object that allows for credential enumeration and exploitation, leading to the leak of plaintext credentials to a malicious host. The attack is facilitated by improper usage of a method that allows operators to add a new host with an attacker-controlled IP, enabling them to retrieve sensitive credentials in plaintext.
