CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-400 The product does not properly control the allocation and maintenance of a limited resource.

Impact Analysis

This vulnerability can lead to a Denial of Service (DoS) condition. An attacker can exploit it by sending crafted SQL queries that cause the Virtuoso database server to crash, making the service unavailable to legitimate users until it is restarted or recovered.

Executive Summary

The CVE-2025-61025 vulnerability is a flaw in the sslr_qst_get component of openlink virtuoso-opensource version 7.2.11. It allows attackers to cause the database server to crash by sending specially crafted SQL queries. The issue occurs during the processing of these malicious SQL statements, which triggers a failure in the query execution engine, specifically in the sslr_qst_get function.

Detection Guidance

This vulnerability can be detected by attempting to reproduce the crash using the proof-of-concept (PoC) SQL query that triggers the issue in the sslr_qst_get function of Virtuoso 7.2.11.

One suggested method is to run the PoC SQL file inside a Docker container running Virtuoso 7.2.11. Executing this maliciously crafted SQL query will cause the server to fail, indicating the presence of the vulnerability.

No specific network detection commands are provided, but testing the database server with the PoC SQL query is the recommended approach.

Compliance Impact

The vulnerability causes a Denial of Service (DoS) by crashing the Virtuoso database server when processing crafted SQL queries. However, there is no information provided about any impact on data confidentiality or integrity.

Since the vulnerability does not affect the confidentiality or integrity of data, but only availability, its impact on compliance with standards like GDPR or HIPAA—which emphasize data protection and privacy—is limited to potential service disruption.

No explicit details are given about how this DoS vulnerability affects compliance with these regulations.

Mitigation Strategies

To mitigate the CVE-2025-61025 vulnerability, immediate steps include avoiding the execution of untrusted or crafted SQL statements that could trigger the crash in the sslr_qst_get component.

Additionally, running Virtuoso in a controlled environment such as a Docker container can help reproduce and understand the issue, but it is recommended to restrict access to the database to trusted users only.

Monitoring for updates or patches from the maintainers of openlink virtuoso-opensource and applying them as soon as they become available is also advised.
