CVE-2026-1480
Published: 27 January 2026
Summary
CVE-2026-1480 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-2026-1480 is an out-of-band SQL injection (OOB SQLi) vulnerability in the Performance Evaluation (EDD) application developed by Gabinete Técnico de Programación. The flaw resides in the 'Id_usuario' parameter within the '/evaluacion_objetivos_anyo_sig_evalua.aspx' endpoint, enabling attackers to extract sensitive information from the underlying database through external channels without the application directly returning the data. This compromises the confidentiality of stored information, as scored at CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and mapped to CWE-89.
Remote attackers require no privileges or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation allows extraction of sensitive database contents via out-of-band techniques, such as DNS or HTTP requests to attacker-controlled servers, bypassing direct application responses and enabling unauthorized data disclosure.
The INCIBE-CERT advisory at https://www.incibe.es/en/incibe-cert/notices/aviso/out-band-sql-injection-quatuor-performance-evaluation details the vulnerability, though specific mitigation steps or patches are not outlined in available information. Security practitioners should review the advisory for implementation guidance and apply input validation or parameterized queries to the affected parameter.
