CVE-2026-1483: Out-of-band SQL injection in Quatuor Performance Evaluation

An out-of-band SQL injection vulnerability (OOB SQLi) has been detected in the Performance Evaluation (EDD) application developed by Gabinete Técnico de Programación. Exploiting this vulnerability in the parameter 'Id_usuario' in '/evaluacion_objetivos_ver_auto.aspx', could allow an attacker to extract sensitive information from the database through external channels, without the affected application returning the data directly, compromising the confidentiality of the stored information.

Security readout for executives and security teams

Plain-English summary

CVE-2026-1483 is a critical SQL injection issue in Quatuor Evaluación de Desempeño (EDD). An unauthenticated network attacker could abuse a user ID parameter to make the application database send sensitive data through external channels. The main business risk is confidentiality loss from HR or performance evaluation data stored in the system.

Executive priority

Treat this as urgent if Quatuor EDD is deployed, especially if externally reachable. Prioritize asset confirmation, access restriction, and vendor remediation tracking. The issue can expose sensitive employee evaluation data and has a critical CVSS score, but public sources provided do not confirm active exploitation.

Technical view

INCIBE describes an out-of-band SQL injection in Quatuor Performance Evaluation EDD at /evaluacion_objetivos_ver_auto.aspx through the Id_usuario parameter. The CVE maps to CWE-89 and has CVSS 4.0 score 9.3: network exploitable, low complexity, no privileges, no user interaction, with high confidentiality and integrity impact.

Likely exposure

Organizations using Quatuor Evaluación de Desempeño (EDD) should assume exposure until they verify deployment status and vendor guidance. The CVE record lists all versions as affected. Internet-facing or partner-accessible EDD instances would carry higher urgency than internally isolated deployments.

Exploitation context

The sources do not state active exploitation, and the CVE is not listed as KEV in the provided bundle. The vulnerability is still high concern because exploitation requires no privileges or user interaction and can extract database information indirectly through outbound channels.

Researcher notes

Evidence is limited to CVE and INCIBE details. No public patch, fixed version, workaround, or exploit-in-the-wild claim is included in the provided sources. Avoid assumptions beyond Quatuor EDD, all versions affected, Id_usuario parameter, and the named ASPX endpoint.

Mitigation direction

  • Identify any Quatuor EDD deployments and owners immediately.
  • Check INCIBE and vendor guidance for patches, fixed versions, or workarounds.
  • Restrict network access to EDD, especially from the internet.
  • Limit database and application outbound connectivity where business-safe.
  • Increase monitoring for suspicious EDD requests and unusual outbound database-related traffic.

Validation and detection

  • Confirm whether Quatuor EDD is installed and reachable in your environment.
  • Verify whether /evaluacion_objetivos_ver_auto.aspx is present on EDD instances.
  • Review web logs for unusual Id_usuario parameter activity.
  • Review DNS, HTTP, and database egress logs for unexpected external callbacks.
  • Document current version and compare against vendor or INCIBE remediation guidance.
