CVE-2023-29005

Flask-AppBuilder versions before 4.3.0 lack rate limiting which can allow an attacker to brute-force user credentials. Version 4.3.0 includes the ability to enable rate limiting using AUTH_RATE_LIMITED = True, RATELIMIT_ENABLED = True, and setting an AUTH_RATE_LIMIT.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.

Affected Software

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]
