Published: 27 January 2026
Summary
CVE-2026-1475 is a critical-severity SQL Injection (CWE-89) vulnerability in Quatuor Evaluacion De Desempeno. Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 24.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-1475 is an out-of-band SQL injection (OOB SQLi) vulnerability affecting the Performance Evaluation (EDD) application developed by Gabinete Técnico de Programación. The flaw resides in the 'Id_usuario' parameter within the '/evaluacion_acciones_evalua.aspx' endpoint, enabling attackers to extract sensitive information from the underlying database through external channels without the application directly returning the data. This issue, linked to CWE-89, carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), highlighting high confidentiality impact with no requirements for privileges or user interaction.
Remote, unauthenticated attackers can exploit this vulnerability over the network with low complexity. By injecting malicious payloads into the vulnerable parameter, they can trigger out-of-band data exfiltration, such as via DNS or HTTP requests to attacker-controlled servers, allowing retrieval of confidential database contents like user data or other stored information.
The INCIBE-CERT advisory at https://www.incibe.es/en/incibe-cert/notices/aviso/out-band-sql-injection-quatuor-performance-evaluation details this vulnerability and is the primary reference for further guidance on detection and response.
