CVE-2020-7374

Estado: ModificadaAlta (7.8)—💥 Exploit

Documalis Free PDF Editor version 5.7.2.26 and Documalis Free PDF Scanner version 5.7.2.122 do not appropriately validate the contents of JPEG images contained within a PDF. Attackers can exploit this vulnerability to trigger a buffer overflow on the stack and gain remote code execution as the user running the Documalis Free PDF Editor or Documalis Free PDF Scanner software.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
