CVE-2024-11131
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 · uneditedA vulnerability regarding out-of-bounds read is found in the video interface. This allows remote attackers to execute arbitrary code via unspecified vectors. The following models with Synology Camera Firmware versions before 1.2.0-0525 may be affected: BC500, CC400W and TC500.
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 · high confidenceAn out-of-bounds read vulnerability exists in the video interface of Synology BC500, CC400W, and TC500 camera firmware versions prior to 1.2.0-0525. This memory corruption issue allows remote attackers to execute arbitrary code without authentication, earning a critical CVSS score of 9.8.

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.
-
Identify camera modelLocate the Synology camera model number on the physical device label or in the device's web interface under System Information or Device Status.Affected if The model is BC500, CC400W, or TC500.
-
Check firmware versionAccess the camera web interface and navigate to System > Firmware or System > About. Alternatively, use the Synology app or SSH to the device and run: cat /etc/os-release or look for version info in the system settings.Affected if The displayed firmware version is lower than 1.2.0-0525.
-
Confirm video interface is enabledIn the camera web interface, verify that the video streaming or RTSP service is enabled under Network Settings or Streaming Settings.Affected if Video interface streaming is active, as this is the vulnerable component.
-
Assess network exposureCheck if the camera's web interface or video ports (typically 80, 443, 554 for RTSP) are exposed to untrusted networks. Review router/firewall rules and camera network configuration.Affected if The camera is directly accessible from the internet or untrusted networks without proper firewall segmentation.
You are affected if you have a BC500, CC400W, or TC500 camera running firmware version lower than 1.2.0-0525 with the video 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.
dbcve · scoped1.2.0-0525
Upgrade all affected Synology camera models (BC500, CC400W, TC500) to firmware version 1.2.0-0525 or later to remediate the out-of-bounds read vulnerability.
1.2.0-0525
- Download firmware version 1.2.0-0525 or later for your specific camera model (TC500, CC400W, or BC500) from the official Synology download center
- Log in to the Synology Surveillance Station or the camera's web interface
- Navigate to the camera settings or firmware update section
- Upload and install the downloaded firmware file
- After the update completes, verify the firmware version displays as 1.2.0-0525 or later to confirm the patch was applied
