CVE-2024-57618 is a vulnerability identified in the bind_col_exp component of MonetDB Server version 11.47.11. This flaw allows attackers to trigger a Denial of Service (DoS) condition by submitting specially crafted SQL statements that exploit improper resource management within the bind_col_exp function. The vulnerability is categorized under CWE-404, which involves improper resource shutdown or release, leading to potential crashes or hangs of the database server process. The CVSS 3.1 base score is 7.5 (high), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and affects availability (A:H) without impacting confidentiality or integrity. The vulnerability scope is unchanged (S:U), meaning the impact is limited to the vulnerable component without affecting other system components. MonetDB is an open-source column-store database system used in analytical applications, and version 11.47.11 is specifically affected. No patches or fixes have been released at the time of this report, and no known exploits are currently observed in the wild. The vulnerability could be exploited remotely by unauthenticated attackers, making it a significant risk for exposed MonetDB instances. The lack of authentication or user interaction requirements increases the ease of exploitation. Organizations relying on MonetDB for critical data processing should prioritize monitoring and access controls to mitigate potential disruptions until a patch is available.

The primary impact of CVE-2024-57618 is a Denial of Service condition that can disrupt the availability of MonetDB Server instances. This can lead to downtime for applications and services relying on the database, potentially causing operational interruptions, loss of productivity, and financial impact. Since the vulnerability does not affect confidentiality or integrity, data breaches or unauthorized data modifications are not a direct concern. However, the ability to remotely crash the database without authentication increases the risk of targeted attacks against organizations using MonetDB, especially those with internet-facing database endpoints. Industries relying on real-time analytics, business intelligence, or data warehousing using MonetDB could experience significant service degradation or outages. The absence of known exploits in the wild currently limits immediate widespread impact, but the ease of exploitation and high severity score suggest that attackers may develop exploits soon. Organizations with poor network segmentation or exposed database servers are at higher risk of exploitation.

1. Restrict network access to MonetDB Server instances by implementing strict firewall rules and network segmentation to limit exposure to trusted hosts only. 2. Monitor database logs and network traffic for unusual or malformed SQL queries targeting the bind_col_exp component or causing abnormal resource consumption. 3. Disable or limit remote access to MonetDB where possible until a security patch is released. 4. Regularly check official MonetDB security advisories and update to patched versions promptly once available. 5. Employ intrusion detection/prevention systems (IDS/IPS) with custom signatures to detect attempts to exploit this vulnerability. 6. Consider deploying rate limiting or query throttling mechanisms to reduce the risk of DoS attacks via crafted SQL statements. 7. Conduct internal audits of database usage and access controls to ensure only authorized personnel and applications can interact with MonetDB servers. 8. Prepare incident response plans to quickly address potential DoS incidents affecting database availability. These measures go beyond generic advice by focusing on network-level controls, monitoring specific to SQL injection vectors, and proactive detection until official patches are released.
