Veeam has patched four vulnerabilities in Backup Enterprise Manager, one of which may allow attackers to bypass authentication and log in to its web interface as any user.
Veeam Backup Enterprise Manager is an application that is used to manage the Veeam Backup & Replication solution – a backup/restore app for virtual and physical machines and cloud-based workloads – via a web console.
The vulnerabilities affect all versions of Veeam Backup & Replication, but they have only been fixed in Veeam Backup Enterprise Manager 12.1.2.172, which is packaged with Veeam Backup & Replication 12.1.2 – the only currently supported version of that solution.
Veeam advises customers who can’t upgrade Veeam Backup Enterprise Manager to 12.1.2.172 to either halt the software or even uninstall it if not in use.
Also: “Veeam Backup Enterprise Manager is compatible with managing Veeam Backup & Replication servers running an older version than Veeam Backup Enterprise Manager. Therefore, if the Veeam Backup Enterprise Manager software is installed on a dedicated server, Veeam Backup Enterprise Manager can be upgraded to version 12.1.2.172 without the need to upgrade Veeam Backup & Replication immediately.”
While there’s no mention of any of the fixed vulnerabilities being exploited in the wild, a vulnerability in Veeam Backup & Replication has been leveraged by financially-motivated attackers last year.
