Improper Authentication in Lin-CMS-Flask v0.1.1 allows remote attackers to launch brute force login attempts without restriction via the login function in the component app/api/cms/user.py.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.

Affected Software

Name Vendor Start Version End Version
Lin-cms-flask Talelin 0.1.1 0.1.1

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.

  • Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
