What to do

AI-suggested

To mitigate CVE-2024-33671, organizations should immediately apply the Veritas Backup Exec 22.2 HotFix 917391 or later updates that address this vulnerability. In the absence of an official patch, administrators should restrict local access to Backup Exec servers to trusted personnel only and implement strict access controls and monitoring to detect unauthorized local activities. Employing host-based intrusion detection systems (HIDS) and file integrity monitoring can help identify suspicious file deletion attempts. Network segmentation and the principle of least privilege should be enforced to limit the ability of attackers to gain local access to backup servers. Regularly auditing backup file integrity and maintaining offline or immutable backup copies can reduce the impact of potential deletions. Additionally, organizations should review and harden the configuration of the Deduplication Multi-threaded Streaming Agent to minimize exposure. Incident response plans should include procedures for rapid recovery if backup files are compromised.

Description

An issue was discovered in Veritas Backup Exec before 22.2 HotFix 917391. The Backup Exec Deduplication Multi-threaded Streaming Agent can be leveraged to perform arbitrary file deletion on protected files.
