Veritas NetBackup Client vulnerability analysis and mitigation

A critical security vulnerability (CVE-2024-28222) has been discovered in Veritas NetBackup, affecting versions before 8.1.2 and NetBackup Appliance before 3.1.2. The vulnerability exists in the NetBackup BPCD process, which inadequately validates file paths, allowing unauthenticated attackers to upload and execute custom files. This vulnerability has received a CVSS v3.1 base score of 9.8, indicating its critical severity (NVD, Veritas Advisory).

The vulnerability (CVE-2024-28222) is classified as a Remote Code Execution (RCE) vulnerability, stemming from insufficient validation of file paths in the NetBackup BPCD process. The critical severity rating (CVSS v3.1 score of 9.8) is based on the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating network accessibility, low attack complexity, no required privileges, and no user interaction needed for exploitation. The vulnerability is also associated with CWE-22 (Improper Limitation of a Pathname to a Restricted Directory) (NVD).

The vulnerability enables attackers to potentially steal sensitive data, access critical backups, deploy ransomware to encrypt backups and disrupt recovery efforts, and gain a foothold within networks to launch wider attacks. Given NetBackup's role in safeguarding organizational data, successful exploitation could lead to devastating consequences, including financial losses and reputational damage (Security Online).

For NetBackup users running versions prior to 8.1.2, upgrading to version 8.3.0.2 or later is recommended. Users of NetBackup Appliance running versions prior to 3.1.2 should upgrade to version 3.3.0.2 MR2 or later. Organizations currently running version 8.1.2 or later of NetBackup, or 3.1.2 or later of NetBackup Appliance, require no immediate action (Veritas Advisory).
