Security readout for executives and security teams
Plain-English summary
CVE-2026-1478 is a critical SQL injection issue in Quatuor Evaluación de Desempeño (EDD). An unauthenticated network attacker could potentially pull sensitive database information through external channels. This is a confidentiality risk for organizations using the named application, especially if it is internet-accessible.
Executive priority
Treat as urgent if your organization uses Quatuor EDD, particularly on externally reachable systems. The main business risk is exposure of sensitive personnel or evaluation data from the database. If EDD is not used, no direct action is indicated beyond confirming absence.
Technical view
The advisory describes out-of-band SQL injection in parameters Id_usuario and Id_evaluacion on /evaluacion_hca_evalua.aspx. CVSS v4.0 is 9.3: network-accessible, low complexity, no privileges, no user interaction, with high confidentiality and integrity impact and low availability impact. The weakness is CWE-89.
Likely exposure
Exposure is limited to organizations running Quatuor Evaluación de Desempeño (EDD), especially deployments reachable from untrusted networks. The source data does not provide clear affected version ranges beyond ambiguous version metadata, so asset confirmation is required.
Exploitation context
The provided sources do not report active exploitation, and this CVE is not marked as CISA KEV. The vulnerability type is serious because out-of-band SQL injection can extract data without returning it directly in the web response.
Researcher notes
Version and fix details are incomplete in the provided sources; affected metadata lists version “0” with defaultStatus “unaffected,” which needs vendor clarification. Avoid assuming broad product impact without deployment evidence. Focus triage on endpoint exposure, application presence, and signs of out-of-band data access.
Mitigation direction
- Check INCIBE and vendor guidance for affected versions and any available fix.
- Prioritize updating or applying vendor-provided remediation when available.
- Restrict access to the EDD application from untrusted networks.
- Increase monitoring for the affected endpoint and unusual database-related outbound activity.
- If internally developed/customized, review input handling and SQL query construction.
Validation and detection
- Inventory systems running Quatuor Evaluación de Desempeño (EDD).
- Confirm whether /evaluacion_hca_evalua.aspx is present and reachable.
- Determine whether EDD is internet-facing or accessible by untrusted users.
- Review web logs for unusual requests involving Id_usuario or Id_evaluacion.
- Review security monitoring for unexpected outbound DNS or database-triggered external connections.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
