Netbackup: Use of Hard-coded Credentials

Published Updated By the CyberSecBulletin desk

CVE-2022-36952 is a critical-severity use of hard-coded credentials vulnerability in Netbackup from Veritas, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 8.3.0.2 as the first without the flaw, so updating Netbackup to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.53% chance of exploitation within 30 days, which is low compared with other CVEs.

Critical severity: a successful attack would have severe impact.

What to do

  1. Update Netbackup to 8.3.0.2 or a later version.
  2. Read the advisory on veritas.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

In Veritas NetBackup OpsCenter, a hard-coded credential exists that could be used to exploit the underlying VxSS subsystem. This affects 8.x through 8.3.0.2, 9.x through 9.0.0.1, 9.1.x through 9.1.0.1, and 10.

The underlying weakness: Use of Hard-coded Credentials

The product contains hard-coded credentials, such as a password or cryptographic key.

How developers prevent this class of flaw

  • For outbound authentication: store passwords, keys, and other credentials outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible. In Windows environments, the Encrypted File System (EFS) may provide some protection.
  • For inbound authentication: Rather than hard-code a default username and password, key, or other authentication credentials for first time logins, utilize a first login mode that requires the user to enter a unique strong password or key.
  • If the product must contain hard-coded credentials or they cannot be removed, perform access control checks and limit which entities can access the feature that requires the hard-coded credentials. For example, a feature might only be enabled through the system console instead of through a network connection.
