CVE-2026-29516

Estado: AnalizadaMedia (6.9)—

Buffalo TeraStation NAS TS5400R firmware version 4.02-0.06 and prior contain an excessive file permissions vulnerability that allows authenticated attackers to read the /etc/shadow file by uploading and executing a PHP file through the webserver. Attackers can exploit world-readable permissions on /etc/shadow to retrieve hashed passwords for all configured accounts including 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).
