CVE-2017-2851
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn the web management interface in Foscam C1 Indoor HD cameras with application firmware 2.52.2.37, a specially crafted HTTP request can cause a buffer overflow.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceBuffer overflow vulnerability in the web management interface of Foscam C1 Indoor HD cameras (firmware 2.52.2.37). A specially crafted HTTP request can trigger the overflow, potentially allowing remote code execution or denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm device model is Foscam C1 Indoor HDAccess the device web interface or check physical device labeling to verify the model number is C1 Indoor HD CameraAffected if Device is not a Foscam C1 Indoor HD Camera, then not affected by this specific CVE
-
Check firmware versionLog into the web management interface and navigate to Device Settings > Device Information, or access the device's status page to view the firmware versionAffected if Firmware version is exactly 2.52.2.37
-
Verify web management interface is enabledConfirm the web-based management interface is accessible by attempting to reach the device IP on HTTP/HTTPS ports (typically 88 or 443)Affected if Web management interface is disabled or inaccessible, the attack surface is not present
-
Check network exposure of web interfaceReview firewall rules or network configuration to determine if the web management interface is accessible from untrusted networksAffected if Web interface is directly exposed to the internet or untrusted LAN segments, increasing exploitability
Device is affected if it is a Foscam C1 Indoor HD Camera running firmware version 2.52.2.37 with the web management interface enabled and accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate firmware to vendor-provided patch. If update unavailable, restrict network access to the web management interface using firewall rules or VLAN segmentation.
