Summary
Xpand IT Write-back manager v2.3.1 uses a hardcoded salt in the license class configuration, leading to the generation of hardcoded and predictable symmetric encryption keys for license generation and validation. This allows an attacker to reconstruct the keys and forge licenses.
Risk Assessment
Predictable encryption keys may allow an attacker to generate their own valid licenses or bypass licensing mechanisms, potentially resulting in unauthorized access to product features. This can lead to financial losses and license violations.
Recommendation
Upgrade the software to a version that removes the hardcoded salt and uses secure, random keys. If upgrading is not possible, contact the vendor for mitigation guidance.
