Description

A vulnerability in Veeam Backup & Replication allows a low-privileged user to connect to remoting services and exploit insecure deserialization by sending a serialized temporary file collection. This exploit allows the attacker to delete any file on the system with service account privileges. The vulnerability is caused by an insufficient blacklist during the deserialization process.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
