Security readout for executives and security teams
Plain-English summary
Pandora FMS 756 and earlier has a cross-site scripting issue in the service name field. A highly privileged user could store JavaScript that later runs when another user views affected content. Business urgency is mainly for organizations running Pandora FMS with multiple administrators or exposed management access.
Executive priority
Treat as a moderate operational risk. Prioritize remediation where Pandora FMS manages sensitive monitoring data or where several administrators can modify services.
Technical view
CVE-2021-46678 is CWE-79 in Artica PFMS Pandora FMS v756 and below. The CVSS 3.1 score is 4.0 with AV:L/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:L, indicating high privileges and user interaction are required. Sources do not provide exploit details or a named fixed version.
Likely exposure
Exposure is limited to Pandora FMS deployments on version 756 or below, especially where service configuration is handled by multiple privileged users.
Exploitation context
The source bundle does not report active exploitation, and the CVE is not listed as KEV. The CVSS vector suggests exploitation requires high privileges and user interaction.
Researcher notes
Evidence identifies stored XSS in the service form name field. The available sources do not name a patch, mitigation, exploit status, or affected CPEs beyond Pandora FMS v756 and below.
Mitigation direction
- Identify all Pandora FMS instances and prioritize version 756 or below.
- Check Pandora FMS vendor guidance for the fixed or supported release path.
- Restrict service configuration access to trusted administrative users.
- Review service name data for unexpected scripts or markup.
- Limit access to the Pandora FMS management interface.
Validation and detection
- Confirm each Pandora FMS instance version from administrative inventory.
- Review which roles can create or edit service names.
- Inspect recent service name changes by privileged accounts.
- Verify service name rendering is safely encoded after remediation.
- Check vendor advisories for current fix confirmation.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
