WBCE CMS is a content management system. Version 1.6.4 contains a brute-force protection bypass where an attacker can indefinitely reset the counter by modifying X-Forwarded-For on each request, gaining unlimited password guessing attempts, effectively bypassing all brute-force protection. The application fully trusts the X-Forwarded-For header without validating it or restricting its usage. This issue is fixed in version 1.6.5.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.

Affected Software

Name Vendor Start Version End Version
Wbce_cms Wbce * 1.6.5 (excluding)

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]
