Security readout for executives and security teams
Plain-English summary
CVE-2026-1475 is a critical SQL injection flaw in Quatuor Evaluación de Desempeño (EDD). An unauthenticated attacker could use the Id_usuario parameter to pull sensitive database information through out-of-band channels. Organizations using this application should treat exposure as urgent because the issue affects confidentiality and integrity, and the source lists all versions as affected.
Executive priority
High priority. If Quatuor EDD is in use, quickly determine whether it is externally reachable and whether sensitive HR or performance data is stored in its database. Until vendor guidance is confirmed, reduce exposure and increase monitoring.
Technical view
The vulnerability is CWE-89 out-of-band SQL injection in /evaluacion_acciones_evalua.aspx via the Id_usuario parameter. CVSS 4.0 is 9.3: network-exploitable, low complexity, no privileges, no user interaction, with high vulnerable-system confidentiality and integrity impact. The public notice identifies all versions of Quatuor EDD as affected.
Likely exposure
Exposure is likely limited to organizations running Quatuor Evaluación de Desempeño (EDD), especially if the application is reachable from untrusted networks. The source bundle states all versions are affected, but provides no CPEs or deployment details.
Exploitation context
The sources describe unauthenticated, network-based exploitation potential, but do not state active exploitation. The CVE is not marked as CISA KEV in the provided data. No exploit code or public weaponization details are included in the supplied sources.
Researcher notes
Evidence is limited to the CVE record and INCIBE advisory. The affected scope is broad: all versions of Quatuor EDD. No patch, fixed version, indicators of compromise, or confirmed exploitation are provided in the supplied sources.
Mitigation direction
- Identify whether Quatuor EDD is deployed in your environment.
- Check INCIBE and vendor guidance for patches, updates, or mitigations.
- Restrict external access to the EDD application where business allows.
- Monitor database and application logs for unusual out-of-band activity.
- Apply input validation or compensating controls only under vendor-approved guidance.
Validation and detection
- Search asset inventories for Quatuor Evaluación de Desempeño or EDD.
- Confirm whether /evaluacion_acciones_evalua.aspx is present and reachable.
- Review application exposure from internet and partner networks.
- Check logs for suspicious requests involving the Id_usuario parameter.
- Track vendor or INCIBE updates for remediation status.
