An issue in the user login box of LJCMS v1.11 allows attackers to hijack user accounts via brute force attacks.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Ljcms 8cms 1.11 1.11

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]
