This update resolves a critical security flaw in the Veeam Backup Enterprise Manager (VBEM) component and includes numerous stability and performance enhancements. All administrators are strongly advised to apply this patch immediately to safeguard their data infrastructure.

Understanding the Critical Vulnerability: CVE-2024-29855
The central focus of this patch is the resolution of CVE-2024-29855, a broken access control vulnerability with a high severity score.
Here’s what you need to know:
- Impact: This flaw allows an unauthenticated remote attacker to log into the Veeam Backup Enterprise Manager web interface as any user. This means an attacker requires no prior access or credentials to gain control.
- Component Affected: The vulnerability is specific to the Veeam Backup Enterprise Manager (VBEM). If you do not have this component installed and in use, your environment is not exposed to this specific threat. However, the cumulative nature of the patch still makes it highly recommended.
- Risk: A successful exploit could grant an attacker complete control over backup jobs, allowing them to view, modify, or even delete critical backup data, restore sensitive files, or disrupt recovery operations.
Given the ease of exploitation and the potential for catastrophic data loss or breach, patching this vulnerability should be your top priority.
Beyond Security: Additional Fixes and Enhancements
While the security fix is the most urgent reason to update, the P20240529 patch also delivers a range of important bug fixes and stability improvements. These cumulative updates enhance the reliability of your backup operations.
Key enhancements include:
- Tape and GFS Jobs: Resolves issues where Grandfather-Father-Son (GFS) tape jobs could incorrectly identify a backup chain as incomplete, leading to failed runs. It also fixes problems with synthetic full backups on certain tape libraries.
- Object Storage: Addresses bugs related to immutability in Dell Data Domain and HPE StoreOnce repositories. The patch also improves interaction with object storage repositories that use single-region AWS STS endpoints.
- Storage and Platform Support: Fixes an issue where rescanning a NetApp ONTAP storage system could fail. It also resolves errors related to using Veeam VHR tools with Linux Hardened Repositories.
- General Reliability: Corrects various issues, including incorrect license usage calculations after upgrading, UI errors in the console, and performance problems with certain SQL Server transaction log backups.
