Security readout for executives and security teams

Plain-English summary

CVE-2017-2876 is a high-impact flaw in the Foscam C1 Indoor HD Camera. A crafted request to its Multi-Camera interface on port 10000 can trigger a buffer overflow. Successful exploitation could compromise confidentiality, integrity, and availability of the camera.

Executive priority

Treat this as a high-priority asset exposure issue if Foscam C1 cameras are deployed. Focus first on internet-facing or broadly reachable cameras, then confirm vendor remediation options or replacement needs.

Technical view

The issue affects Foscam C1 firmware combination system 1.9.3.18, application 2.52.2.43, and plug-in 3.3.0.26. CVSS 3.0 rates it 8.8 with network access, low complexity, low privileges, no user interaction, and high CIA impact.

Likely exposure

Exposure is likely limited to Foscam C1 Indoor HD Cameras running the listed firmware, especially where port 10000 is reachable from untrusted networks. The source bundle does not identify other Foscam models as affected.

Exploitation context

The provided sources describe an exploitable buffer overflow but do not show CISA KEV listing or other evidence of active exploitation. The CVSS vector indicates exploitation requires network reachability and low privileges, with no user interaction.

Researcher notes

Key uncertainty is remediation: the supplied sources identify the vulnerable firmware and attack surface but do not provide a confirmed patch version. Do not broaden affected scope beyond the listed Foscam C1 firmware without additional vendor evidence.

Mitigation direction

  • Inventory Foscam C1 cameras and record exact firmware versions.
  • Restrict access to port 10000 from untrusted networks.
  • Remove affected cameras from direct internet exposure.
  • Check Foscam guidance for firmware updates or replacement direction.
  • Monitor camera network traffic for unexpected access attempts.

Validation and detection

  • Confirm whether any Foscam C1 devices run application firmware 2.52.2.43.
  • Verify port 10000 is not reachable from the internet.
  • Review firewall rules limiting access to camera management interfaces.
  • Check vulnerability records for any newer vendor remediation guidance.
  • Document compensating controls for devices that cannot be updated.
