CVE-2024-0227: Vulnerability Insights and Analysis

This CVE was published by SNPS on January 11, 2024, and it highlights a vulnerability in the "devise-two-factor" product by Synopsys. The lack of brute force protection in this product can lead to potential security risks.

Understanding CVE-2024-0227

This vulnerability in devise-two-factor allows attackers to bypass the 2FA mechanism through brute-force attacks due to the absence of throttling or login attempt restrictions. The inherent entropy limitations of the Time-based One Time Password algorithm exacerbate this risk.

What is CVE-2024-0227?

The vulnerability in CVE-2024-0227 arises from the failure of the devise-two-factor product to enforce login attempt restrictions, making it susceptible to brute-force attacks. This could potentially compromise the security of user accounts utilizing the 2FA mechanism.

The Impact of CVE-2024-0227

The impact of CVE-2024-0227 is categorized as medium severity. Attackers could exploit this vulnerability to abuse authentication, potentially leading to unauthorized access to user accounts and sensitive information.
