A missing error check exists in the Multi-Camera interface used by the Foscam C1 Indoor HD Camera running application firmware 2.52.2.43. A specially crafted request on port 10001 could allow an attacker to reset the user accounts to factory defaults, without authentication.

Security readout for executives and security teams

Plain-English summary

This flaw lets an unauthenticated network attacker reset user accounts on a vulnerable Foscam C1 Indoor HD Camera to factory defaults. For executives, the concern is loss of camera access control and potential follow-on compromise where these cameras are reachable from untrusted networks.

Executive priority

Prioritize remediation where cameras are reachable beyond a tightly controlled management network. The business risk is not only camera disruption, but loss of credential control on a physical security device.

Technical view

CVE-2017-2877 is a missing error check in the Foscam C1 Multi-Camera interface. The affected build is system firmware 1.9.3.18 with application firmware 2.52.2.43. A crafted request to port 10001 can reset user accounts without authentication. CVSS v3.0 is 9.8 critical.

Likely exposure

Exposure is limited to Foscam C1 Indoor HD Cameras running the cited firmware combination, especially where port 10001 is reachable from the internet, guest networks, shared LANs, or other untrusted segments.

Exploitation context

The bundle does not show CISA KEV listing or cited evidence of active exploitation. The CVSS vector indicates remote, unauthenticated, low-complexity exploitation with no user interaction, so reachable vulnerable cameras should be treated as urgent.

Researcher notes

Evidence is specific to Foscam C1 with application firmware 2.52.2.43. The source bundle does not provide a CWE, patch version, or proof of active exploitation. Avoid broadening scope to other Foscam models without vendor evidence.

Mitigation direction

  • Remove internet exposure for affected cameras and block untrusted access to port 10001.
  • Restrict camera management access to trusted networks or VPN-only administration paths.
  • Check Foscam and Talos guidance for fixed firmware or supported replacement options.
  • If no supported fix exists, isolate or retire affected cameras.
  • After securing access, rotate credentials and re-provision accounts from known-good settings.

Validation and detection

  • Inventory Foscam C1 cameras and record system, application, and plug-in firmware versions.
  • Confirm whether port 10001 is reachable from any untrusted network path.
  • Compare deployed firmware against the affected version listed in CVE and Talos sources.
  • Review camera account configuration for unexpected factory-default or reset states.
  • Document compensating controls where vulnerable devices cannot be updated or replaced.
