CVE-2026-22235

Estado: AnalizadaAlta (8.7)—

OPEXUS eComplaint before version 9.0.45.0 allows an attacker to visit the the 'DocumentOpen.aspx' endpoint, iterate through predictable values of 'chargeNumber', and download any uploaded files.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:N/UI:N permite acceso remoto sin autenticación a endpoint expuesto (T1190). Iteración de valores predecibles para descargar archivos = lectura de datos (T1005).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
