TopControl Suite - Bacnet: Use of Password Hash With Insufficient Computational Effort

Published Updated By the CyberSecBulletin desk

CVE-2022-3010 is a high-severity use of password hash with insufficient computational effort vulnerability in TopControl Suite - Bacnet from Priva, with a CVSS 3.1 base score of 7.5 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 8.7.8.0 as the first without the flaw, so updating TopControl Suite - Bacnet to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.58% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update TopControl Suite - Bacnet to 8.7.8.0 or a later version.
  2. Update TopControl Suite - Blue ID to 8.7.8.0 or a later version.
  3. Update TopControl Suite - Compass to 8.7.8.0 or a later version.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

The Priva TopControl Suite contains predictable credentials for the SSH service, based on the Serial number. Which makes it possible for an attacker to calculate the login credentials for the Priva TopControll suite.

The underlying weakness: Use of Password Hash With Insufficient Computational Effort

The product generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort that would make password cracking attacks infeasible or expensive.

How developers prevent this class of flaw

  • When using industry-approved techniques, use them correctly. Don't cut corners by skipping resource-intensive steps (CWE-325). These steps are often essential for preventing common attacks.
