CVE-2024-57622 is a vulnerability identified in the exp_bin component of MonetDB Server version 11.49.1. MonetDB is an open-source column-store database management system optimized for high-performance analytics. The vulnerability allows attackers to cause a Denial of Service (DoS) condition by submitting crafted SQL statements that exploit a flaw in the exp_bin component. The exp_bin component likely handles binary expression evaluation or processing within the database engine. The vulnerability is classified under CWE-89, which corresponds to SQL Injection, indicating that the crafted SQL statements exploit improper input handling or sanitization, leading to unexpected behavior causing the server to crash or become unresponsive. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) indicates that the attack can be performed remotely over the network without any authentication or user interaction, with low attack complexity and no impact on confidentiality or integrity, but a high impact on availability. The vulnerability was reserved on January 9, 2025, and published on January 14, 2025. No patches or fixes have been released yet, and no known exploits have been observed in the wild. Given the nature of the vulnerability, attackers can disrupt database services, potentially impacting applications and services relying on MonetDB for data processing and analytics.

The primary impact of CVE-2024-57622 is denial of service, which can cause MonetDB servers to crash or become unresponsive. This disruption can lead to downtime for applications and services dependent on the database, resulting in operational interruptions, loss of availability of critical data analytics, and potential financial and reputational damage. Since MonetDB is used in various sectors including research institutions, financial services, and data analytics platforms, the impact can be significant where high availability is required. The lack of required privileges or user interaction lowers the barrier for attackers to exploit this vulnerability remotely, increasing the risk of widespread disruption. However, the absence of confidentiality or integrity impact means data theft or tampering is not a concern with this vulnerability. Organizations with MonetDB deployments exposed to untrusted networks are particularly vulnerable to remote exploitation attempts.

Until an official patch is released, organizations should implement the following mitigations: 1) Restrict network access to MonetDB servers by applying firewall rules or network segmentation to limit connections only to trusted hosts and internal networks. 2) Monitor database logs and network traffic for unusual or malformed SQL queries that could indicate exploitation attempts targeting the exp_bin component. 3) Employ Web Application Firewalls (WAFs) or database activity monitoring tools capable of detecting and blocking suspicious SQL injection patterns. 4) If feasible, temporarily disable or restrict functionalities that allow execution of complex or user-supplied SQL statements involving binary expressions. 5) Maintain up-to-date backups and prepare incident response plans to quickly recover from potential DoS attacks. 6) Stay informed through official MonetDB and CVE channels for patches or updates addressing this vulnerability and apply them promptly once available. 7) Conduct internal security assessments and penetration testing to evaluate exposure and readiness against this vulnerability.
