CVE-2024-22570
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 · uneditedA stored cross-site scripting (XSS) vulnerability in /install.php?m=install&c=index&a=step3 of GreenCMS v2.3 allows attackers to execute arbitrary web scripts or HTML via a crafted payload.
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 stored cross-site scripting (XSS) vulnerability exists in the step3 of the GreenCMS v2.3 installation script (install.php?m=install&c=index&a=step3). User-supplied input in this step is not properly sanitized before being stored and rendered, allowing attackers to inject malicious JavaScript or HTML that executes when other users access the affected page.

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.
-
Confirm Greencms version is 2.3Locate the version file or header in the GreenCMS installation directory. Check for a version.php file, or look at the admin dashboard About page if the CMS is installed.Affected if The installed version is exactly 2.3
-
Verify installation was performedCheck if the CMS was installed by looking for the existence of the database configuration file (often config.php or similar in the /data or /include directory) or by accessing the admin panel.Affected if The installation process was completed, meaning data from step3 was saved to the database or configuration
-
Identify if step3 input is still stored and renderedExamine the database or configuration files for any stored values from the installation step3 form (such as site name, admin credentials, or other fields submitted during installation). Check if these values are displayed anywhere in the application without proper encoding.Affected if Data entered during install step3 was persisted and is rendered in any web page without sanitization
You are affected if running GreenCMS version 2.3 and the installation process (step3) was completed, as the unsanitized user input from that step would be stored and executable when rendered.

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.
From vendor dataApply proper input validation and output encoding/sanitization to all user inputs in the installation step3 form. The fix should escape special characters before displaying any user-provided data back to the browser.
