CVE-2024-55399
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 · unedited4C Strategies Exonaut before v21.6.2.1-1 was discovered to contain a Server-Side Request Forgery (SSRF).
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 confidence4C Strategies Exonaut before version v21.6.2.1-1 contains a Server-Side Request Forgery (SSRF) vulnerability. This flaw allows an attacker to induce the server to make arbitrary requests to internal or external resources, potentially accessing sensitive internal services or bypassing network segmentation.

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 Exonaut versionCheck the application's version information, typically found in the software's about page, a version file, or by querying the application directly (e.g., look for a /version endpoint, check installation logs, or review the software's metadata files)Affected if The installed version is less than 21.6.2.1-1, or the installed version equals 22.0
-
Locate URL-fetching featuresReview the Exonaut configuration and application features for any functionality that accepts user-supplied URLs, such as webhooks, URL preview, external resource loading, or API integrations. Check configuration files for entries related to URL handling or external request modulesAffected if URL-fetching or external request features are enabled and accessible to users
-
Verify network exposureExamine the application's network configuration and firewall rules to determine if the server can make outbound HTTP/HTTPS requests to internal or external resourcesAffected if The application server has outbound network access and SSRF-preventive controls are not in place
You are affected if Exonaut is installed at a version below 21.6.2.1-1 (or at exactly version 22.0) and URL-handling features are accessible to users.
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 · scoped21.6.2.1-1
Upgrade Exonaut to version v21.6.2.1-1 or later. Additionally, implement strict input validation on any user-supplied URLs, enforce network segmentation, and restrict outbound connections from the application server to minimize the impact of SSRF attacks.
v21.6.2.1-1 or later (contact vendor for version 22.0 fix)
- Contact 4C Strategies to obtain the specific fixed release for version 22.0 and any interim versions
- Upgrade Exonaut to version 21.6.2.1-1 or later (or the latest stable release if 22.0 was patched in a subsequent release)
- After upgrading, verify the SSRF vulnerability is resolved through testing
- Review any new security configurations introduced in the fixed version
