CVE-2022-39058 is a path traversal vulnerability (CWE-22) identified in the RAVA certificate validation system developed by Changing Information Technology Inc., specifically affecting version 3 of the product. This vulnerability allows an unauthenticated remote attacker to bypass authentication mechanisms by exploiting improper limitation of pathname inputs to restricted directories. By manipulating file path parameters, the attacker can access arbitrary system files outside the intended directory scope. The vulnerability does not require any user interaction or privileges, making it remotely exploitable over the network with low attack complexity. The CVSS v3.1 base score is 7.5 (high severity), reflecting the high confidentiality impact due to unauthorized file access, while integrity and availability remain unaffected. Although no known exploits have been reported in the wild, the nature of the vulnerability poses a significant risk as it could lead to exposure of sensitive information, such as configuration files, private keys, or other critical data stored on the system running the RAVA certificate validation software. Given that this system is involved in certificate validation, compromise or unauthorized access could undermine trust in digital certificates and related security processes.

For European organizations, the impact of this vulnerability can be substantial, especially for entities relying on the RAVA certificate validation system for managing digital certificates and ensuring secure communications. Unauthorized access to system files could lead to leakage of sensitive cryptographic material or configuration data, potentially enabling further attacks such as man-in-the-middle, impersonation, or lateral movement within networks. This could affect sectors with high reliance on secure certificate validation, including financial institutions, government agencies, telecommunications providers, and critical infrastructure operators. The breach of confidentiality could result in regulatory non-compliance under GDPR due to exposure of personal or sensitive data. Additionally, the erosion of trust in certificate validation processes could disrupt secure communications and transactions, impacting business continuity and reputation.

To mitigate this vulnerability, organizations should prioritize updating or patching the RAVA certificate validation system to a version where the path traversal flaw is fixed, if available. In the absence of an official patch, implementing strict input validation and sanitization on all file path parameters used by the application can reduce risk. Deploying web application firewalls (WAFs) with rules to detect and block path traversal attempts may provide interim protection. Restricting file system permissions to limit the application's access to only necessary directories and files can minimize potential damage. Network segmentation and access controls should be enforced to limit exposure of the vulnerable system to untrusted networks. Regular security audits and monitoring for unusual file access patterns or authentication bypass attempts are recommended. Finally, organizations should review and harden their certificate management processes to detect anomalies that could arise from exploitation of this vulnerability.
