CVE-2017-2805
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 · uneditedAn exploitable stack-based buffer overflow vulnerability exists in the web management interface used by the Foscam C1 Indoor HD Camera. A specially crafted http request can cause a stack-based buffer overflow resulting in overwriting arbitrary data on the stack frame. An attacker can simply send an http request to the device to trigger this vulnerability.
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 analysisThe program writes past the bounds of a buffer, overwriting adjacent memory an attacker can turn to their advantage. Crafted input can overwrite control data and redirect execution. Remediation is validating every index and length before a write, plus modern memory-safety mitigations.

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.
dbcve · scopedFoscam C1 Indoor HD Camera firmware version higher than 1.9.3.17 (contact Foscam support for exact fixed release number)
- 1. Identify the current firmware version of the Foscam C1 Indoor HD Camera by accessing the device's web management interface.
- 2. Navigate to the camera's settings or system information page to view the installed firmware version.
- 3. If the current firmware version is 1.9.3.17 or lower, download the latest firmware update from the official Foscam support website (support.foscam.com) or through the Foscam mobile application.
- 4. Follow the manufacturer's documented firmware upgrade procedure, typically found in the camera's user manual.
- 5. After upgrading, verify the new firmware version displays correctly in the web interface.
- 6. Confirm the vulnerability is remediated by ensuring the web management interface properly handles malformed HTTP requests without crashing or allowing code execution.
