CVE-2019-25061 Explained : Impact and Mitigation

The Ruby gem, known as random_password_generator or RandomPasswordGenerator, utilizes the Kernel#rand function to generate passwords. However, this approach can make it easier to predict passwords due to the cyclic nature of the function.

Understanding CVE-2019-25061

The random_password_generator (aka RandomPasswordGenerator) gem through 1.0.0 for Ruby uses Kernel#rand to generate passwords, which, due to its cyclic nature, can facilitate password prediction.

What is CVE-2019-25061?

The CVE-2019-25061 vulnerability is associated with the random_password_generator gem in Ruby, which employs the Kernel#rand function for password generation, potentially leading to predictable passwords.

The Impact of CVE-2019-25061

This vulnerability can compromise the security of systems and applications that rely on the random_password_generator gem by making generated passwords easier to predict, posing a risk to sensitive data.
