CVE-2023-29005: 
Python vulnerability analysis and mitigation

Flask-AppBuilder versions before 4.3.0 lack rate limiting functionality which can allow attackers to brute-force user credentials. The vulnerability (CVE-2023-29005) was disclosed on April 10, 2023, affecting all versions prior to 4.3.0. This security issue specifically impacts the database authentication mechanism of Flask-AppBuilder (GitHub Advisory).

The vulnerability has been assigned a CVSS v3.1 base score of 7.5 HIGH with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N. The vulnerability is classified as CWE-307 (Improper Restriction of Excessive Authentication Attempts). The issue stems from the lack of built-in rate limiting mechanisms in the authentication system, which makes it susceptible to brute force attacks (NVD).

The absence of rate limiting on authentication attempts allows attackers to perform unlimited login attempts, potentially leading to unauthorized access through credential brute-forcing. This could result in compromised user accounts and unauthorized access to protected resources (GitHub Advisory).

The vulnerability has been patched in version 4.3.0. Users should upgrade to this version and enable rate limiting by setting AUTH_RATE_LIMITED = True and RATELIMIT_ENABLED = True. The rate limit can be configured using AUTH_RATE_LIMIT. For systems unable to upgrade, implementing rate limiting through a reverse proxy or other external strategies is recommended as a workaround (GitHub Advisory, Flask Limiter).
