Trend Micro ID Security, version 3.0 and below contains a vulnerability that could allow an attacker to send an unlimited number of email verification requests without any restriction, potentially leading to abuse or denial of service.
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]
