An issue was discovered on Innovaphone PBX before 14r1 devices. The password form, used to authenticate, allows a Brute Force Attack through which an attacker may be able to access the administration panel
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.
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]
