The Web UI component of Mitel MiVoice 6800 and 6900 series SIP Phones with firmware before 5.1.0.SP5 could allow an unauthenticated attacker to expose sensitive information due to improper memory handling during failed login attempts.
Weakness
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.

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]
