CVE-2024-57644 is a vulnerability identified in the itc_hash_compare component of OpenLink Virtuoso OpenSource version 7.2.11, a multi-model database engine widely used for data integration and semantic web applications. The flaw arises from improper handling of SQL statements, allowing attackers to craft malicious SQL queries that trigger a Denial of Service (DoS) condition. This vulnerability is categorized under CWE-89, indicating it is a form of SQL Injection, where the attacker can manipulate SQL queries to disrupt normal database operations. The vulnerability requires no authentication or user interaction, making it remotely exploitable over the network. Although the primary impact is a DoS condition affecting system integrity by causing service disruption, there is no direct impact on confidentiality or availability beyond the DoS effect. No patches or fixes have been published yet, and no known exploits have been observed in the wild. The CVSS v3.1 base score of 7.5 reflects the ease of remote exploitation and the significant impact on system integrity. Organizations using this specific version of Virtuoso should monitor for vendor updates and consider interim mitigations such as input sanitization and limiting exposure of the database to untrusted networks.

The vulnerability allows attackers to cause a Denial of Service on affected systems, leading to disruption of database services that rely on OpenLink Virtuoso OpenSource 7.2.11. This can result in downtime for applications dependent on the database, impacting business continuity, data processing, and service availability indirectly. Since the vulnerability does not require authentication or user interaction, it can be exploited by remote attackers, increasing the risk of widespread disruption. Organizations with critical infrastructure, research databases, or semantic web applications using Virtuoso may face operational interruptions. While confidentiality is not directly impacted, the integrity of database operations is compromised due to the injection of crafted SQL statements causing service failure. The lack of known exploits in the wild currently reduces immediate risk, but the potential for future exploitation remains high given the ease of attack and the severity score.

1. Monitor OpenLink's official channels for patches or updates addressing CVE-2024-57644 and apply them promptly once available. 2. Implement strict input validation and sanitization on all SQL queries interacting with the Virtuoso database to prevent injection of malicious statements. 3. Restrict network access to the Virtuoso database server by using firewalls and network segmentation, limiting exposure to trusted hosts only. 4. Employ Web Application Firewalls (WAFs) or SQL injection detection tools to detect and block suspicious SQL queries targeting the database. 5. Regularly audit and monitor database logs for unusual query patterns indicative of attempted exploitation. 6. Consider deploying rate limiting or query throttling to mitigate the impact of potential DoS attempts. 7. If feasible, upgrade to a later, unaffected version of Virtuoso once a patched release is available. 8. Educate development and operations teams about secure coding practices to avoid SQL injection vulnerabilities in applications interfacing with the database.
