Security readout for executives and security teams
Plain-English summary
CVE-2026-1473 is a critical SQL injection issue in Quatuor’s Performance Evaluation / EDD application. An unauthenticated attacker could potentially extract sensitive database information indirectly, without the web page displaying it. If this system stores employee evaluation or HR data, confidentiality risk is high.
Executive priority
Treat as urgent if Quatuor EDD is deployed, especially if it is reachable from the internet. The main business risk is exposure of sensitive employee or organizational data. Immediate inventory, access restriction, and vendor guidance checks are warranted.
Technical view
The issue is an out-of-band SQL injection in the Id_usuario parameter of /evaluacion_competencias_evalua.aspx. The CVE lists network attack, low complexity, no privileges, and no user interaction, with CVSS 4.0 score 9.3. Affected scope is Quatuor Evaluación de Desempeño / EDD, all versions.
Likely exposure
Exposure is likely for organizations running Quatuor EDD where the vulnerable page is reachable by attackers. The source bundle says all versions are affected. Internet-facing deployments or broadly reachable internal deployments should be prioritized first.
Exploitation context
The provided sources do not state active exploitation, and the CVE is not marked KEV. The scoring indicates exploitation does not require authentication or user interaction. Out-of-band SQL injection may depend on database/network conditions that allow external data channels.
Researcher notes
Evidence is limited to the CVE record and INCIBE advisory reference in the source bundle. No public patch details, workaround, or exploitation-in-the-wild claim is provided. Validate exposure without using destructive or offensive testing, and focus on endpoint reachability, logging, and egress paths.
Mitigation direction
- Check Quatuor, Gabinete Técnico de Programación, and INCIBE guidance for patches or vendor instructions.
- Identify and prioritize any internet-facing EDD instances.
- Restrict access to the EDD application to trusted networks or VPN where feasible.
- Review database and application egress controls for unnecessary external connectivity.
- Increase monitoring for suspicious requests to the affected endpoint and unusual outbound database activity.
Validation and detection
- Inventory Quatuor EDD deployments and confirm whether the vulnerable endpoint exists.
- Confirm product version and affected status against vendor or INCIBE guidance.
- Determine whether the application is internet-facing or broadly reachable internally.
- Review web logs for unusual access to /evaluacion_competencias_evalua.aspx.
- Review DNS, HTTP, and database egress logs for unexpected external destinations.
