CVE-2025-61025
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue in the sslr_qst_get component of openlink virtuoso-opensource v7.2.11 allows attackers to cause a Denial of Service (DoS) via crafted SQL statements.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA denial of service vulnerability exists in the sslr_qst_get component of OpenLink Virtuoso Open-Source v7.2.11. Attackers can cause the service to become unavailable by submitting specially crafted SQL statements that trigger the vulnerability in the query processing component.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify OpenLink Virtuoso installation and versionRun the command 'virtuoso --version' or check for the virtuoso-server process (e.g., 'ps aux | grep virtuoso') to confirm the product and obtain the exact version number installedAffected if The installed version is exactly v7.2.11 (the vulnerable version listed in the CVE)
-
Verify SQL query service is accessibleCheck if the Virtuoso SQL port (default 1111) is listening and accessible by running 'netstat -tlnp | grep 1111' or 'ss -tlnp | grep 1111' to confirm the service is exposedAffected if The Virtuoso SQL service is listening and accessible (the sslr_qst_get component processes SQL queries submitted to this service)
-
Confirm network exposure of the database interfaceReview firewall rules or network configuration to determine if the SQL service port is exposed to untrusted networks. Check /etc/firewalld/rules.xml, iptables rules, or cloud security groups as applicableAffected if The SQL interface is reachable from network segments containing untrusted users (the attack requires submitting malicious SQL statements)
-
Check query timeout configurationInspect the Virtuoso INI configuration file (typically virtuoso.ini) for any [Query] section and timeout settings, or check if a query timeout mechanism is implemented at the application layerAffected if No query timeout limits are configured, allowing crafted queries to run indefinitely and cause DoS
You are affected if running OpenLink Virtuoso v7.2.11 and the SQL query service (sslr_qst_get component) is accessible to untrusted users without query timeout protections.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor patch when available. Until then, restrict database access to trusted users only, implement query timeout limits, and consider network-level filtering to limit exposure to untrusted sources.
