ASPECT®-Enterprise: Use of Weak Credentials
CVE-2023-0635 is a critical-severity use of weak credentials vulnerability in ASPECT®-Enterprise from ABB, 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 3.07.01 as the first without the flaw, so updating ASPECT®-Enterprise to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.37% 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
- Update ASPECT®-Enterprise to 3.07.01 or a later version.
- Update NEXUS Series to 3.07.01 or a later version.
- Update MATRIX Series to 3.07.01 or a later version.
- Read the advisory on search.abb.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.

The underlying weakness: Use of Weak Credentials
The product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker.
How developers prevent this class of flaw
- When the user changes or sets a password, check the password against a database of already compromised or breached passwords. These passwords are likely to be used in password guessing attacks.
