CVE-2021-47795

Estado: AplazadaAlta (8.7)—

GeoVision GeoWebServer 5.3.3 contains multiple vulnerabilities including local file inclusion, cross-site scripting, and remote code execution through improper input sanitization. Attackers can exploit the WebStrings.srf endpoint by manipulating path traversal and injection parameters to access system files and execute malicious scripts.

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 acceso remoto sin privilegios apunta a T1190. CWE-22 (path traversal) y LFI permiten lectura de archivos (T1005); RCE mencionado en WebStrings.srf sugiere T1059 como impacto secundario.

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.
