CVE-2024-3263 in VIS Pro
Summary
by MITRE • 05/14/2024
YMS VIS Pro is an information system for veterinary and food administration, veterinarians and farm. Due to a combination of improper method for system credentials generation and weak password policy, passwords can be easily guessed and enumerated through brute force attacks. Successful attacks can lead to unauthorised access and execution of operations based on assigned user permissions. This vulnerability affects VIS Pro in versions <= 3.3.0.6. This vulnerability has been mitigated by changes in authentication mechanisms and implementation of additional authentication layer and strong password policies.

The CVE-2024-3263 vulnerability affects YMS VIS Pro, a critical information system used in veterinary and food administration that serves veterinarians and farm operations. This system handles sensitive agricultural and animal health data, making unauthorized access particularly concerning for public health and food safety. The vulnerability stems from a fundamental flaw in the system's authentication architecture where credentials generation methods lack proper cryptographic randomness and entropy. This weakness, combined with a weak password policy that does not enforce minimum complexity requirements or rate limiting mechanisms, creates a significant security gap that adversaries can exploit.
The technical implementation flaw represents a classic case of inadequate authentication controls that aligns with CWE-259 and CWE-307 vulnerabilities, specifically addressing weak password policies and improper credential handling. The system's inability to generate sufficiently random passwords and its lack of account lockout mechanisms or rate limiting creates an environment where brute force attacks can systematically guess valid credentials. Attackers can leverage automated tools to rapidly test common password combinations or employ dictionary attacks against the system's user base, exploiting the predictable credential generation patterns that characterize weak authentication implementations. This vulnerability particularly affects versions up to 3.3.0.6, indicating that the developers identified and addressed these weaknesses through enhanced authentication mechanisms.
The operational impact of this vulnerability extends beyond simple unauthorized access, as successful exploitation allows attackers to execute operations based on the assigned user permissions within the veterinary and food administration system. This could potentially lead to data manipulation, unauthorized certification issuance, or access to sensitive animal health records that could compromise public health safety protocols. The vulnerability creates a pathway for adversaries to disrupt critical agricultural operations and potentially cause widespread harm to food safety systems. From an attack perspective, this vulnerability maps to several ATT&CK techniques including credential access through brute force methods and privilege escalation based on compromised credentials.
The mitigation implemented by the developers addresses the core issues through enhanced authentication mechanisms that likely include improved password generation algorithms with sufficient entropy, implementation of strong password policies with complexity requirements, and addition of multi-factor authentication layers. These changes align with industry best practices for authentication security and help prevent the types of brute force and credential guessing attacks that were previously possible. The enhanced authentication layer likely includes account lockout mechanisms, rate limiting, and improved credential validation processes that prevent the systematic enumeration attacks that characterized the original vulnerability. The remediation demonstrates proper security engineering practices that align with NIST SP 800-63B guidelines for authentication and the principle of least privilege in system access control.
