CVE-2020-8634

Estado: ModificadaAlta (7.8)—

Wing FTP Server v6.2.3 for Linux, macOS, and Solaris sets insecure permissions on files modified within the HTTP file management interface, resulting in files being saved with world-readable and world-writable permissions. If a sensitive system file were edited this way, a low-privilege user may escalate privileges to root.

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).
