Deeper analysisAI
CVE-2026-1477 is an out-of-band SQL injection (OOB SQLi) vulnerability, classified under CWE-89, in the Performance Evaluation (EDD) application developed by Gabinete Técnico de Programación. The issue affects the parameters 'Id_usuario' and 'Id_evaluacion' in the '/evaluacion_competencias_evalua_old.aspx' endpoint. It enables attackers to extract sensitive information from the database through external channels without the application directly returning the data, thereby compromising the confidentiality of stored data. The vulnerability was published on 2026-01-27 and has 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).
Unauthenticated remote attackers can exploit this vulnerability over the network with low complexity and no user interaction required. By injecting malicious payloads into the vulnerable parameters, attackers can trigger out-of-band data exfiltration, allowing them to retrieve sensitive database contents indirectly via attacker-controlled external channels, such as DNS or HTTP requests.
