CVE-2026-1479
Published: 27 January 2026
Summary
CVE-2026-1479 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 SC-37 (Out-of-band Channels) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2026-1479 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 parameters 'Id_usuario' and 'Id_evaluacion' within the '/evaluacion_hca_ver_auto.asp' endpoint, enabling attackers to extract sensitive information from the database through external channels without the application directly returning the data. This compromises the confidentiality of stored information and is rated with 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), mapped to CWE-89. The vulnerability was published on 2026-01-27.
Any unauthenticated remote attacker can exploit this vulnerability with low complexity and no user interaction required. By injecting malicious payloads into the vulnerable parameters, the attacker can trigger database queries that exfiltrate sensitive data via out-of-band channels, such as DNS or HTTP requests to attacker-controlled servers, bypassing traditional in-band SQLi detection and response mechanisms.
INCIBE-CERT has issued an advisory detailing the vulnerability, available at https://www.incibe.es/en/incibe-cert/notices/aviso/out-band-sql-injection-quatuor-performance-evaluation. Security practitioners should consult this reference for specific mitigation guidance, such as input validation, parameterized queries, or application updates if available.
