CVE-2022-50897

Estado: ModificadaAlta (8.7)—

mPDF 7.0 contains a local file inclusion vulnerability that allows attackers to read arbitrary system files by manipulating annotation file parameters. Attackers can generate URL-encoded or base64 payloads to include local files through crafted annotation content with file path specifications.

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.

Vulnerabilidad LFI en mPDF (AV:N, PR:N, UI:N) permite lectura de ficheros arbitrarios del sistema mediante manipulación de parámetros de anotación. CWE-98 (dynamic code execution) y descripción explícita de 'read arbitrary system files' indicando confidencialidad (VC:H).

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.
