Security readout for executives and security teams
Plain-English summary
CVE-2026-1479 is a critical SQL injection flaw in Quatuor Evaluación de Desempeño (EDD). An unauthenticated attacker could use vulnerable request parameters to make the application extract sensitive database information through external channels. Organizations using this product should treat exposure as urgent, especially if the application is reachable from untrusted networks.
Executive priority
Prioritize within the emergency remediation queue if Quatuor EDD is in use. The vulnerability can expose confidential database information without authentication or user interaction. If the system is internet-facing, reduce exposure immediately while tracking vendor or INCIBE remediation guidance.
Technical view
The issue is CWE-89 out-of-band SQL injection in /evaluacion_hca_ver_auto.asp involving Id_usuario and Id_evaluacion. The CVSS 4.0 score is 9.3, with network access, low complexity, no privileges, and no user interaction required. Sources state all versions of Quatuor EDD are affected.
Likely exposure
Highest risk applies where Quatuor EDD is internet-facing or accessible by untrusted users. Internal-only deployments still carry risk from compromised users, VPN access, or lateral movement. The source bundle identifies all versions as affected, but does not provide deployment prevalence or patch availability.
Exploitation context
The source describes potential extraction of sensitive database information via out-of-band channels. CISA KEV status is false in the provided data, and no cited source confirms active exploitation. No exploit maturity or public proof-of-concept information is provided in the source bundle.
Researcher notes
Evidence is limited to the CVE record and INCIBE notice. The affected product is Quatuor Evaluación de Desempeño, all versions. The vulnerable parameters and endpoint are named, but the sources do not provide a fixed version, workaround, or confirmed exploitation details.
Mitigation direction
- Identify whether Quatuor Evaluación de Desempeño is deployed and reachable.
- Restrict access to trusted networks until vendor guidance is available.
- Check INCIBE and vendor advisories for patches or official mitigations.
- Monitor for unusual outbound database, DNS, or HTTP activity from application hosts.
- Review web application firewall rules for SQL injection detection coverage.
Validation and detection
- Inventory Quatuor EDD instances and confirm affected version scope.
- Confirm exposure of /evaluacion_hca_ver_auto.asp from external and internal networks.
- Review application logs for suspicious requests to the affected endpoint.
- Check egress logs for unusual outbound callbacks from database or application servers.
- Document whether vendor patches or configuration guidance have been applied.
