An issue was discovered in DSK DSKNet 2.16.136.0 and 2.17.136.5. It mishandles access control. This allows a remote attacker to access account information pages (including personal data) without being authenticated. The collected information includes the badge numbers that operate as user login names. They have a PIN code. The PIN code is 4 digits and thus can be guessed in 10000 brute force attempts.
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]
