CVE-2024-57615 is a vulnerability identified in the BATcalcbetween_intern component of MonetDB Server version 11.47.11. This flaw allows an unauthenticated attacker to cause a Denial of Service (DoS) condition by submitting specially crafted SQL queries. The vulnerability is classified under CWE-89, which relates to improper neutralization of special elements used in an SQL command ('SQL Injection'). However, in this case, the impact is limited to availability disruption rather than data breach or modification. The CVSS v3.1 base score is 7.5, indicating a high severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impact limited to availability (A:H) with no confidentiality or integrity impact. The vulnerability exploits a flaw in the internal calculation function BATcalcbetween_intern, which likely mishandles certain SQL inputs leading to resource exhaustion or server crash. No patches or exploits are currently publicly available, but the vulnerability is officially published and reserved as of January 2025.

The primary impact of CVE-2024-57615 is the potential for Denial of Service attacks against MonetDB Server instances. This can lead to service outages, disrupting business operations that rely on MonetDB for data processing and analytics. Organizations using MonetDB in critical environments may face downtime, loss of productivity, and potential financial losses. Since the vulnerability does not affect confidentiality or integrity, data theft or tampering is not a direct risk. However, repeated or sustained DoS attacks could degrade trust in the affected services and require costly incident response and recovery efforts. The ease of exploitation without authentication and user interaction increases the risk of opportunistic attacks, especially in exposed network environments.

Until an official patch is released, organizations should implement network-level protections such as firewall rules to restrict access to MonetDB Server instances to trusted IP addresses only. Employing Web Application Firewalls (WAFs) or SQL query filtering mechanisms can help detect and block suspicious or malformed SQL statements targeting the BATcalcbetween_intern function. Monitoring database server logs for unusual query patterns or crashes can provide early warning signs of exploitation attempts. Additionally, running MonetDB Server with the least privileges necessary and isolating it within segmented network zones reduces the attack surface. Once patches become available, prompt application of updates is critical. Organizations should also review and harden their SQL query validation and input sanitization practices to prevent injection-like attacks.
