CVE-2017-2872: Insufficient security checks exist in the recovery procedure used by the Foscam C1 Indoor HD Camera running...

Insufficient security checks exist in the recovery procedure used by the Foscam C1 Indoor HD Camera running application firmware 2.52.2.43. A HTTP request can allow for a user to perform a firmware upgrade using a crafted image. Before any firmware upgrades in this image are flashed to the device, binaries as well as arguments to shell commands contained in the image are executed with elevated privileges.

Security readout for executives and security teams

Plain-English summary

This flaw affects Foscam C1 indoor cameras. A low-privileged user who can reach the camera over the network may abuse the recovery firmware-upgrade process so attacker-controlled content runs with elevated privileges. That could compromise confidentiality, integrity, and availability of the camera.

Executive priority

Prioritize remediation for any affected camera reachable outside a trusted management network. The issue can lead to full device compromise, and cameras often sit in sensitive physical environments with weak monitoring.

Technical view

CVE-2017-2872 is an insufficient security check in the Foscam C1 recovery procedure for application firmware 2.52.2.43. The CVSS 3.0 vector is AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H. Crafted firmware images may execute binaries and shell-command arguments with elevated privileges before flashing.

Likely exposure

Exposure is likely limited to Foscam Indoor IP Camera C1 Series devices matching the listed firmware set, especially if their HTTP management or recovery interface is reachable by untrusted users or networks.

Exploitation context

The source bundle does not show CISA KEV listing or confirmed active exploitation. The vulnerability is network-reachable, low-complexity, and requires low privileges, so exposed cameras should be treated as high-risk assets.

Researcher notes

Evidence identifies one affected firmware combination and a Talos advisory reference. The bundle does not include a named patch, exploit-in-the-wild confirmation, or broader model coverage, so avoid extending impact beyond the Foscam C1 details provided.

Mitigation direction

  • Check Foscam and Talos guidance for fixed firmware or vendor-supported remediation.
  • Remove camera HTTP management interfaces from internet and guest-network exposure.
  • Restrict administration to trusted networks, VPNs, or isolated management segments.
  • Limit camera accounts to necessary users and rotate credentials.
  • Retire or replace affected devices if no supported firmware is available.

Validation and detection

  • Inventory Foscam C1 cameras and record system, application, and plug-in firmware versions.
  • Flag devices running application firmware 2.52.2.43 with the listed firmware set.
  • Verify HTTP management and recovery interfaces are not externally reachable.
  • Review device history for unexpected firmware updates, reboots, or configuration changes.
