CVE-2023-41815
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 · uneditedImproper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Pandora FMS on all allows Cross-Site Scripting (XSS). Malicious code could be executed in the File Manager section. This issue affects Pandora FMS: from 700 through 774.
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 File Manager section of Pandora FMS versions 700 through 774. The application fails to properly sanitize user-supplied input, allowing malicious JavaScript code to be injected and executed in the context of other users' browsers when they access the File Manager.

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 Pandora FMS installation and versionLocate the Pandora FMS installation directory or check the version via the web interface (typically at /pandora_console/ or by examining the version file in the installation root). Use commands like 'grep -r "7.0"' or check the version.php file if it exists in the installation.Affected if The installed version is found to be between 700 and 774 inclusive
-
Confirm File Manager module is accessibleLog into the Pandora FMS web console and navigate to the File Manager section (typically under Operations or Administration menus). Alternatively, check if the File Manager feature is enabled in the system configuration files.Affected if The File Manager section is accessible to any user account in the system
-
Review File Manager for suspicious uploaded contentAccess the File Manager interface and examine all uploaded files. Look for files with unusual names, unexpected file types, or files containing JavaScript code (check .html, .txt, or image files for script tags). Inspect file contents directly if the interface allows viewing.Affected if Any file in the File Manager contains JavaScript code, script tags, or suspicious content that was not intentionally uploaded by an administrator
-
Check browser console for XSS indicatorsOpen a browser, navigate to the Pandora FMS File Manager section, and open the browser developer console (F12). Look for any JavaScript errors, unexpected script executions, or console logs that indicate injected scripts are running.Affected if JavaScript code executes automatically or console shows script-related errors when viewing File Manager entries
The environment is affected if Pandora FMS versions 700 through 774 are installed AND the File Manager module is accessible, as the stored XSS flaw allows arbitrary JavaScript injection through uploaded file names or content.

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 · scopedImplement proper input validation and output encoding for all user-supplied data in the File Manager section. Apply context-aware escaping before rendering any user input in HTML. Consider implementing a Content Security Policy (CSP) header as a defense-in-depth measure.
Upgrade to Pandora FMS version 775 or later (the first version after the affected range 700-774)
- 1. Identify the current Pandora FMS version in use (check in the console footer or via 'admin > setup > general' page)
- 2. If version is between 700 and 774 inclusive, plan an upgrade to version 775 or later
- 3. Before upgrading, backup the entire Pandora FMS database and configuration files
- 4. Review the official Pandora FMS upgrade documentation for your current version
- 5. Perform the upgrade following standard upgrade procedures for Pandora FMS
- 6. After upgrade, verify the File Manager section is accessible and functioning correctly
- 7. Confirm the version number has updated in the console to a version > 774
