An Improper Restriction of Excessive Authentication Attempts [CWE-307] in FortiSIEM below 7.0.0 may allow a non-privileged user with access to several endpoints to brute force attack these endpoints.
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]
