CVE-2020-12508
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 image-relocator 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 confidencePath traversal vulnerability in the image-relocator module of s::can moni::tools allows unauthenticated attackers to read arbitrary files from the device by manipulating file path references (e.g., using ../ sequences). Affects versions below 4.2.

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 for version information in the application metadata, about screen, or version file (typically named version.txt, info.ini, or displayed in the software UI under Help > About)Affected if The installed version is below 4.2 (e.g., 4.1.x, 4.0.x, or earlier)
-
Verify image-relocator module presenceSearch for the image-relocator module within the s::can moni::tools installation directory; look for files or folders named 'image-relocator', 'imagerelocator', or similar, and check configuration files for module enablementAffected if The image-relocator module is present and enabled in the configuration
-
Review network exposure of the image-relocator serviceExamine network configuration or firewall rules to determine if the image-relocator service is accessible from untrusted network segments; check if the service binds to all interfaces (0.0.0.0) versus localhost onlyAffected if The service is exposed to unauthenticated network access without proper access controls
-
Inspect web server or API logs for path traversal attemptsReview access logs for the image-relocator endpoint looking for suspicious patterns such as '../', '..\', or encoded variations (e.g., %2e%2e%2f) in file path parametersAffected if Recent log entries contain path traversal sequences targeting the image-relocator functionality
A system is affected if s::can moni::tools version is below 4.2 AND the image-relocator module is present and accessible, as this combination allows the path traversal flaw to be exploited by remote attackers.

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 to s::can moni::tools version 4.2 or later which contains the patch for proper path validation. If immediate upgrade is not possible, restrict network access to the affected service and monitor for suspicious file access patterns.
4.2
- Upgrade s::can moni::tools to version 4.2 or later to remediate the path traversal vulnerability
- Contact s::can (www.s-can.at) for specific upgrade instructions and download access
