New Veeam vulnerability advisory notice

This advisory is for organizations that use Veeam ONE to monitor virtual infrastructure, backup infrastructure, and data protection environments. If your organization does not use this platform, this notification may be discarded.

Summary
Veeam has released hotfixes to address four vulnerabilities, two of them critical, present in the Veeam ONE platform. The first critical vulnerability may allow an unauthenticated user to gain information about the SQL server connection that Veeam ONE uses to access its configuration data base, introducing the potential for an attacker to perform remote code execution on the SQL server hosting the database.

The second critical vulnerability may be leveraged to leak the NTLM hash of the account used by the Veeam ONE Reporting Services to an unprivileged user with access to the UI.
