Estado: AnalizadaCrítica (9.8)—

Stirling-PDF is a locally hosted web application that performs various operations on PDF files. Prior to version 1.1.0, the "convert file to pdf" functionality (/api/v1/convert/file/pdf) uses LibreOffice's unoconvert tool for conversion, and SSRF vulnerabilities exist during the conversion process. This issue has been patched in version 1.1.0.

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.

SSRF en endpoint web /api/v1/convert/file/pdf (AV:N/AC:L/PR:N), permitiendo proxy SSRF (T1090) y acceso a recursos internos (T1005, CWE-918).

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.
