CVE-2018-3917
Estado: ModificadaCrítica (9.9)—
On Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17, the video-core process insecurely extracts the fields from the "shard" table of its SQLite database, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability. The strcpy call overflows the destination buffer, which has a size of 16 bytes. An attacker can send an arbitrarily long "region" value in order to exploit this vulnerability.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
- Puntuación base: 9.9
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.95%
- Percentil entre todas las CVEs puntuadas: 60
- Fecha de la puntuación: 7/10/2026
