CVE-2022-33756 is a high-severity insufficient entropy vulnerability in CA Automic Automation, 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. Affected CA Automic Automation versions: 12.2, 12.3. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.29% chance of exploitation within 30 days, higher than 71% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of CA Automic Automation you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on support.broadcom.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
CA Automic Automation 12.2 and 12.3 contain an entropy weakness vulnerability in the Automic AutomationEngine that could allow a remote attacker to potentially access sensitive data.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Insufficient Entropy
The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.
How developers prevent this class of flaw
- Determine the necessary entropy to adequately provide for randomness and predictability. This can be achieved by increasing the number of bits of objects such as keys and seeds.
Timeline
- CVE record published.
- Record last changed materially (score, affected products, status or references).
