CVE-2020-12509
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 s::can moni::tools in versions below 4.2 an unauthenticated attacker could get any file from the device by path traversal in the camera-file module.
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 confidences::can moni::tools versions below 4.2 contain an unauthenticated path traversal vulnerability in the camera-file module, allowing remote attackers to read arbitrary files from the device filesystem by manipulating file path inputs.

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 installed s::can moni::tools versionLocate the s::can moni::tools installation directory and check the version information file, or run the version command for the software if availableAffected if The version is below 4.2 (for example, 4.0, 4.1, or any version number less than 4.2)
-
Confirm camera-file module presenceExamine the software configuration or module list to determine if the camera-file module is installed or enabledAffected if The camera-file module is present and active in the installation
-
Verify network exposure of camera-file interfaceCheck network configuration, firewall rules, or service bindings to determine if the camera-file module interface is accessible over the networkAffected if The camera-file module interface is exposed to the network without authentication restrictions
-
Review access logs for path traversal patternsExamine server or application logs for requests containing traversal sequences such as ../ or absolute path references targeting the camera-file endpointAffected if Suspicious path traversal patterns are present in the logs for the camera-file module
Your environment is affected if s::can moni::tools version is below 4.2 AND the camera-file module is enabled and network-accessible, allowing unauthenticated attackers to manipulate file path inputs and read arbitrary files.
Generated from the published advisory. Verify against your own configuration.
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 · scoped4.2
Upgrade s::can moni::tools to version 4.2 or later to obtain the patched software. If immediate upgrade is not possible, restrict network access to the camera-file module interface and monitor for suspicious path traversal patterns in requests.
s::can moni::tools version 4.2 or later
- 1. Identify the current version of s::can moni::tools installed on the device
- 2. Obtain the version 4.2 or later from the official vendor (www.s-can.at)
- 3. Review upgrade documentation and release notes for the target version
- 4. Schedule a maintenance window for the upgrade
- 5. Backup current configuration before performing the upgrade
- 6. Apply the upgrade to s::can moni::tools to version 4.2 or later
- 7. Verify the installation and test that the camera-file module functions correctly
- 8. Confirm the path traversal vulnerability is resolved by attempting to access files outside the intended directory
