Overview

AI description

Automated description summarized from trusted sources.

CVE-2024-40711 is a critical unauthenticated Remote Code Execution (RCE) vulnerability affecting Veeam Backup & Replication software. It stems from a deserialization of untrusted data, which, when exploited with a malicious payload, allows attackers to execute arbitrary code remotely without needing authentication. This poses a significant risk to organizations relying on Veeam for their backup and data protection strategies. The vulnerability affects Veeam Backup & Replication version 12.1.2.172 and all earlier versions. A successful exploit could grant an attacker full control of the system, enabling them to manipulate data and move laterally within the network. Veeam has released a security patch in version 12.2.0.334 to address this vulnerability, and users are strongly advised to upgrade their systems.

Description: A deserialization of untrusted data vulnerability with a malicious payload can allow an unauthenticated remote code execution (RCE).
