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.

Mitigation Strategies

To mitigate the Denial of Service vulnerability in openlink virtuoso-opensource v7.2.11 caused by crafted SQL statements targeting the t_set_push component, immediate steps include avoiding execution of untrusted or complex SQL queries that resemble the Proof of Concept (PoC) involving CREATE TABLE and UPDATE statements with complex subqueries.

Additionally, if you are using Docker containers for Virtuoso, consider removing old containers and restarting new instances to ensure a clean environment, as demonstrated in the reproduction steps.

Monitoring for updates or patches from the maintainers is also recommended since no CVSS score or official patch information is provided.

Compliance Impact

The provided information does not include any details about the impact of this vulnerability on compliance with common standards and regulations such as GDPR or HIPAA.

Executive Summary

This vulnerability exists in the t_set_push component of openlink virtuoso-opensource version 7.2.11. It allows attackers to cause a Denial of Service (DoS) by sending specially crafted SQL statements.

Impact Analysis

The impact of this vulnerability is that an attacker can cause a Denial of Service (DoS) condition, potentially making the affected service unavailable or unresponsive by exploiting the t_set_push component with crafted SQL statements.

Detection Guidance

This vulnerability can be detected by executing a specific Proof of Concept (PoC) SQL query that triggers a crash in the t_set_push component of Virtuoso 7.2.11. The PoC involves a CREATE TABLE statement followed by an UPDATE with a complex subquery including a CROSS JOIN and SUM aggregation.

To detect the vulnerability on your system, you can run the PoC SQL script against your Virtuoso 7.2.11 instance and observe if it causes a crash or Denial of Service.

  • Remove any old Virtuoso Docker container if present.
  • Start a new Virtuoso instance using the beta Docker image.
  • Execute the PoC SQL query through the Docker container to reproduce the issue.
