OpenClinic GA versions 5.09.02 and 5.89.05b may allow an attacker to bypass the system’s account lockout protection, which may allow brute force password attacks.

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
Openclinic_ga Openclinic_ga_project 5.09.02 (including) 5.09.02 (including)
Openclinic_ga Openclinic_ga_project 5.89.05b (including) 5.89.05b (including)

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]
