Timing Attack Vulnerability in Authentication Mechanism
A vulnerability in the authentication mechanism of the software version 20240310 allows attackers to guess passwords based on the timing of each character's verification. This issue was identified in the 'gaizhenbiao/chuanhuchatgpt' project and involves the use of a simple equality check for password verification, which is susceptible to timing attacks.

Remediation Steps
- Update the authentication mechanism to use a constant-time comparison function for passwords.
- Ensure that all authentication attempts take the same amount of time, regardless of the correctness of the password entered.
- Implement rate limiting and account lockout mechanisms to prevent attackers from making too many password guess attempts in a short period.
- Monitor authentication attempts for patterns that may indicate a timing attack is being attempted.
