CVE-2024-55401
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 issue in 4C Strategies Exonaut before v22.4 allows attackers to execute a directory traversal.
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 confidenceA directory traversal vulnerability in 4C Strategies Exonaut before v22.4 allows attackers to manipulate file paths using '..' sequences or absolute paths to access files outside the intended directory boundaries, potentially exposing sensitive system files or configuration data.

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 Exonaut installation and versionLocate the Exonaut application installation directory or check the application's about/help section for the version number. Common locations include /opt/exonaut, C:\Program Files\4C Strategies\Exonaut, or the application's web interface metadata.Affected if Version is < 21.6.2.1-1 OR (>= 22.0 AND < 22.4)
-
Compare version against affected rangesDocument the installed version and compare it to the affected ranges: versions before 21.6.2.1-1, and versions from 22.0 up to but not including 22.4.Affected if Installed version falls into any of the affected ranges (< 21.6.2.1-1 or >= 22.0 but < 22.4)
-
Verify web interface accessibilityCheck if the Exonaut web interface is exposed and accessible. This typically runs on port 8080, 8443, or configured HTTP/HTTPS ports. Identify any endpoints that handle file paths, uploads, or file retrieval.Affected if Web interface is accessible AND version is in affected range
-
Inspect file path handling endpointsReview the application's available endpoints for any that accept file path parameters, particularly those used for document retrieval, attachments, or file downloads. These are the vectors where directory traversal '..' sequences could be injected.Affected if File path parameters exist in the application AND version is affected
The environment is affected if Exonaut version is less than 21.6.2.1-1, or between 22.0 and 22.3.x inclusive, and the web interface with file path handling is 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 · scoped21.6.2.1-122.4
Upgrade to Exonaut v22.4 or later which contains the directory traversal fix; prior to upgrade, implement strict input validation on file path parameters and restrict file system permissions to limit exposure.
Exonaut v22.4
- Identify current Exonaut version by checking the application or system documentation
- Download Exonaut v22.4 or later from the official vendor distribution channel
- Review upgrade documentation and release notes for any prerequisites
- Create a full backup of the current Exonaut installation and database
- Test the upgrade in a non-production environment first
- Execute the upgrade process following vendor-provided installation instructions
- Verify the installation completed successfully
- Confirm the vulnerability is remediated by checking the version number
