An insufficient entropy vulnerability in the SecuSUITE Secure Client Authentication (SCA) Server of SecuSUITE versions 5.0.420 and earlier could allow an attacker to potentially enroll an attacker-controlled device to the victim’s account and telephone number.
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]
