ASPECT-Enterprise: Use of a One-Way Hash with a Predictable Salt
CVE-2024-13951 is a high-severity use of a one-way hash with a predictable salt vulnerability in ASPECT-Enterprise from ABB, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected ASPECT-Enterprise versions: 3.* and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.21% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

The underlying weakness: Use of a One-Way Hash with a Predictable Salt
The product uses a one-way cryptographic hash against an input that should not be reversible, such as a password, but the product uses a predictable salt as part of the input.
How developers prevent this class of flaw
- If a technique that requires extra computational effort can not be implemented, then for each password that is processed, generate a new random salt using a strong random number generator with unpredictable seeds. Add the salt to the plaintext password before hashing it. When storing the hash, also store the salt. Do not use the same salt for every password.
