CVE-2024-57617 identifies a vulnerability in the dameraulevenshtein component of MonetDB Server version 11.49.1. This component is responsible for computing the Damerau-Levenshtein distance, a string metric for measuring the difference between two sequences. The vulnerability allows an attacker to craft specific SQL statements that exploit improper handling within this component, leading to a Denial of Service (DoS) condition. The CVSS v3.1 score of 7.5 (high) reflects that the attack vector is network-based (AV:N), requires no privileges (PR:N), and no user interaction (UI:N), with a scope unchanged (S:U). The impact is solely on availability (A:H), with no confidentiality or integrity loss. The vulnerability is categorized under CWE-89, which typically relates to SQL Injection issues, suggesting that the crafted SQL statements may exploit input validation weaknesses. Although no patches or known exploits are currently available, the vulnerability poses a risk of service disruption for systems running the affected MonetDB version. MonetDB is an open-source column-store database often used in data analytics and scientific applications, so availability interruptions can affect critical data processing workflows.

The primary impact of CVE-2024-57617 is the potential for Denial of Service attacks against MonetDB Server instances running version 11.49.1. Organizations using MonetDB for data analytics, business intelligence, or scientific research could experience service outages, disrupting data availability and operational continuity. Since the vulnerability can be exploited remotely without authentication, attackers could target exposed MonetDB servers to cause downtime, impacting internal users and external clients relying on database services. Although there is no direct data breach or data integrity compromise, the loss of availability can lead to significant operational and financial consequences, especially in environments where MonetDB supports critical decision-making or real-time analytics. The absence of known exploits in the wild currently reduces immediate risk, but the ease of exploitation and lack of required privileges make it a credible threat once exploit code becomes available.

Until an official patch is released, organizations should implement specific mitigations to reduce exposure. These include restricting network access to MonetDB servers by using firewalls or network segmentation to limit connections only to trusted hosts. Monitoring and logging SQL queries for unusual or malformed statements targeting the dameraulevenshtein function can help detect attempted exploitation. Applying rate limiting or query timeouts may mitigate the impact of crafted queries designed to cause resource exhaustion. Administrators should also review and harden database user permissions to minimize exposure, even though authentication is not required for exploitation, to reduce attack surface. Keeping MonetDB installations updated and subscribing to vendor security advisories will ensure timely application of patches once available. Additionally, consider deploying intrusion detection/prevention systems (IDS/IPS) with signatures tuned to detect anomalous SQL activity related to this vulnerability.
