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 · unedited
A vulnerability was detected in kalcaddle kodbox up to 1.64. This affects an unknown function of the component shareMake/shareCheck. Performing a manipulation of the argument siteFrom/siteTo results in server-side request forgery. The attack is possible to be carried out remotely. The complexity of an attack is rather high. The exploitability is reported as difficult. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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 confidence

Server-side request forgery (SSRF) vulnerability in kalcaddle kodbox up to v1.64 in the shareMake/shareCheck component. The siteFrom/siteTo arguments are not properly validated, allowing an attacker to control the server's outbound requests to arbitrary URLs, potentially accessing internal services or cloud metadata.

MitigationImplement strict allowlist-based input validation on the siteFrom/siteTo parameters to restrict requests to trusted domains only. Additionally, enforce network segmentation and disable unnecessary outbound connectivity from the server to prevent exploitation of this SSRF.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if kodbox is installed
    Locate kodbox installation directories or check web server configuration for kodbox-related virtual hosts or document roots
    Affected if kodbox software is present on the server
  2. Determine the installed kodbox version
    Check version file in the kodbox installation directory or access the application admin panel version information
    Affected if the installed version falls within the affected version range and has not been patched
  3. Verify the shareMake/shareCheck component is accessible
    Attempt to access the shareMake or shareCheck endpoints through the web interface or direct URL request to confirm the feature is enabled
    Affected if the shareMake/shareCheck component is accessible and functional in the installation
  4. Confirm parameter exposure for siteFrom/siteTo
    Inspect HTTP requests to the shareMake/shareCheck endpoints or review application source code for parameter handling
    Affected if the siteFrom and siteTo parameters accept user-supplied URL values without strict validation
  5. Check network outbound access from the server
    Review server firewall rules or proxy configurations to determine if the application server can initiate outbound HTTP connections
    Affected if the server has unrestricted outbound network access, allowing potential SSRF exploitation

A user is affected if kodbox is installed with an unpatched version that includes the vulnerable shareMake/shareCheck component, and the server can make outbound HTTP requests.

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.

Mitigation

Implement strict allowlist-based input validation on the siteFrom/siteTo parameters to restrict requests to trusted domains only. Additionally, enforce network segmentation and disable unnecessary outbound connectivity from the server to prevent exploitation of this SSRF.
