CVE-2022-39056 is a critical SQL Injection vulnerability (CWE-89) found in version 3 of the RAVA certificate validation system developed by Changing Information Technology Inc. The vulnerability arises due to insufficient validation of user-supplied input, allowing an unauthenticated remote attacker to inject arbitrary SQL commands into the backend database queries. This flaw enables the attacker to perform unauthorized actions such as reading sensitive data, modifying records, or deleting database entries. The vulnerability has a CVSS 3.1 base score of 9.8, indicating a critical severity level with network attack vector, low attack complexity, no privileges or user interaction required, and impacts confidentiality, integrity, and availability at a high level. The RAVA system is used for certificate validation, which is a critical security function in IT environments, meaning exploitation could undermine trust in digital certificates and related security mechanisms. Although no known exploits are currently reported in the wild, the ease of exploitation and severity make this a significant threat that requires immediate attention. The lack of available patches at the time of reporting further elevates the risk for organizations using this product.

For European organizations, the exploitation of this vulnerability could have severe consequences. Given that RAVA is a certificate validation system, a successful attack could compromise the integrity and availability of certificate validation processes, potentially allowing attackers to bypass security controls that rely on trusted certificates. This could lead to unauthorized access to sensitive systems, data breaches, and disruption of services dependent on certificate validation. The ability to modify or delete database records could also result in denial of service or manipulation of validation results, undermining trust in digital identities and secure communications. Organizations in sectors such as finance, healthcare, government, and critical infrastructure, which heavily rely on certificate-based authentication and encryption, would be particularly impacted. Additionally, the critical nature of this vulnerability means that attackers could automate exploitation attempts, increasing the risk of widespread compromise across European entities using the affected software.

European organizations using RAVA certificate validation system version 3 should immediately assess their exposure to this vulnerability. Since no official patches are currently available, organizations should implement the following specific mitigations: 1) Restrict network access to the RAVA system to trusted internal networks and limit exposure to the internet using firewalls and network segmentation. 2) Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the RAVA system. 3) Conduct thorough input validation and sanitization at the application layer if possible, or deploy reverse proxies that can filter malicious payloads. 4) Monitor database and application logs for unusual queries or anomalies indicative of injection attempts. 5) Prepare incident response plans to quickly isolate and remediate affected systems if exploitation is detected. 6) Engage with Changing Information Technology Inc. for updates on patches or mitigations and plan for rapid deployment once available. 7) Consider alternative certificate validation solutions if immediate patching is not feasible and risk is unacceptable.
