An issue was discovered in weijiang1994 university-bbs (aka Blogin) in commit 9e06bab430bfc729f27b4284ba7570db3b11ce84 (2025-01-13). A weak verification code generation mechanism combined with missing rate limiting allows attackers to perform brute-force attacks on verification codes without authentication. Successful exploitation may result in account takeover via password reset or other authentication bypass methods.

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]
