CVE-2018-3880: An exploitable stack-based buffer overflow vulnerability exists in the database 'find-by-cameraId' function...

An exploitable stack-based buffer overflow vulnerability exists in the database 'find-by-cameraId' functionality of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The video-core process incorrectly handles existing records inside its SQLite database, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability.

Security readout for executives and security teams

Plain-English summary

This CVE affects Samsung SmartThings Hub STH-ETH-250 firmware 0.20.17. A flaw in the hub’s video-core HTTP server can overflow memory when handling camera database records. If triggered by an attacker meeting the stated access requirements, it could compromise confidentiality, integrity, and availability of the device.

Executive priority

Treat as high priority where affected hubs remain deployed, especially in environments where physical security, cameras, or automation depend on them. The main business risk is compromise or disruption of smart-building control infrastructure.

Technical view

The vulnerability is a stack-based buffer overflow in video-core’s database find-by-cameraId functionality. The process mishandles existing SQLite records, and an HTTP request can trigger the flaw. CVSS 3.0 is 8.2 with local attack vector, low complexity, high privileges, no user interaction, changed scope, and high CIA impact.

Likely exposure

Exposure appears limited to Samsung SmartThings Hub STH-ETH-250 devices running firmware 0.20.17. The source bundle does not identify other models, firmware versions, cloud services, or operating systems as affected.

Exploitation context

The CVE is not listed as KEV in the provided data. The sources describe the vulnerability as exploitable and HTTP-triggerable, but provide no cited evidence of active exploitation in the wild.

Researcher notes

The record is specific but incomplete for remediation. It names firmware 0.20.17 and the vulnerable function, but the supplied sources do not name a patched version. CVSS access requirements should be considered when assessing reachable exposure.

Mitigation direction

  • Inventory Samsung SmartThings Hub STH-ETH-250 devices and firmware versions.
  • Check Samsung or SmartThings guidance for fixed firmware or replacement options.
  • Restrict hub HTTP or administrative access to trusted local administrators.
  • Segment affected hubs from sensitive networks until vendor guidance is confirmed.
  • Monitor affected hubs for crashes, unexpected restarts, or video-core failures.

Validation and detection

  • Confirm whether any STH-ETH-250 hub runs firmware version 0.20.17.
  • Review network exposure of hub HTTP services and administrative paths.
  • Check asset records for SmartThings hubs in sensitive physical locations.
  • Review logs or monitoring for abnormal hub instability or service failures.
