Vulnerability from fkie_nvd - Published: 2018-08-23 15:29 - Updated: 2026-06-17 01:58
Severity
8.5 (High) - CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H
9.9 (Critical) - CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Summary
An exploitable buffer overflow vulnerability exists in the remote video-host communication of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17. The video-core process insecurely parses the AWSELB cookie while communicating with remote video-host servers, leading to a buffer overflow on the heap. An attacker able to impersonate the remote HTTP servers could trigger this vulnerability.
