Unauthorised access to the call forwarding service system in MeetMe products in versions prior to 2024-09 allows an attacker to identify multiple users and perform brute force attacks via extensions.

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]
