CVE-2025-61024
Description
A flaw was found in virtuoso-opensource. An attacker could send specially crafted SQL (Structured Query Language) statements to a specific component, sqlo_try_in_loop, leading to a Denial of Service (DoS). This could make the service unavailable to legitimate users.
Mitigation
To reduce the attack surface, restrict network access to the virtuoso-opensource service to only trusted clients using firewall rules. If the virtuoso-opensource service is not actively used, consider disabling it.
To disable the service:
`sudo systemctl stop virtuoso-opensource`
`sudo systemctl disable virtuoso-opensource`
Applying firewall rules to limit access to the service's port (e.g., 1111/tcp) from specific trusted IP addresses can also reduce exposure.
`sudo firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="<TRUSTED_IP_ADDRESS>" port port="1111" protocol="tcp" accept'`
`sudo firewall-cmd --reload`
Disabling the service will prevent its functionality. A service restart or system reboot may be required for changes to take full effect.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
