An Improper Restriction of Excessive Authentication Attempts issue was discovered in Belden Hirschmann RS, RSR, RSB, MACH100, MACH1000, MACH4000, MS, and OCTOPUS Classic Platform Switches. An improper restriction of excessive authentication vulnerability in the web interface has been identified, which may allow an attacker to brute force authentication.
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]
