A vulnerability exists in the UNEM server / APIGateway that if exploited allows a malicious user to perform an arbitrary number of authentication attempts using different passwords, and eventually gain access to other components in the same security realm using the targeted account.
Weakness
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.

Potential Mitigations
Common protection mechanisms include:
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
