CVE-2024-57625 is a vulnerability identified in the merge_table_prune_and_unionize component of MonetDB Server version 11.49.1. This flaw allows attackers to craft specific SQL statements that trigger a Denial of Service (DoS) condition, effectively crashing or rendering the database server unresponsive. The issue stems from improper handling of SQL queries within this component, which likely leads to resource exhaustion or unhandled exceptions causing service disruption. The vulnerability is remotely exploitable over the network without requiring any authentication or user interaction, increasing its risk profile. The CVSS v3.1 score of 7.5 reflects a high severity, driven primarily by the impact on availability and ease of exploitation. The vulnerability is categorized under CWE-89, which relates to SQL Injection, indicating that the crafted SQL statements exploit weaknesses in input validation or query processing. No patches or mitigations have been officially released at the time of publication, and no active exploitation has been reported. MonetDB is an open-source column-store database system used in analytical workloads, so disruption can affect data processing and analytics pipelines.

The primary impact of CVE-2024-57625 is a Denial of Service condition that can disrupt database availability. Organizations relying on MonetDB for critical data analytics, reporting, or warehousing may experience downtime, leading to operational delays and potential financial losses. Since the vulnerability does not affect confidentiality or data integrity, the risk of data breach or corruption is low. However, the ease of remote exploitation without authentication means attackers can cause service outages from external networks, potentially as part of broader attack campaigns or ransomware operations. This could affect sectors such as finance, telecommunications, research institutions, and government agencies that utilize MonetDB for large-scale data processing. Extended downtime could also impact dependent applications and services, cascading into broader business disruptions.

Until an official patch is released, organizations should implement strict network-level access controls to limit exposure of MonetDB servers to untrusted networks. Deploy firewall rules or VPNs to restrict database access only to authorized users and systems. Monitor database logs and network traffic for unusual or malformed SQL queries that may indicate exploitation attempts. Consider deploying Web Application Firewalls (WAFs) or SQL query analyzers that can detect and block suspicious query patterns targeting the merge_table_prune_and_unionize component. Regularly back up critical data to enable rapid recovery in case of service disruption. Engage with MonetDB maintainers or community forums for updates on patches or workarounds. Where possible, isolate MonetDB instances in segmented network zones to reduce blast radius. Finally, prepare incident response plans specifically addressing database DoS scenarios.
