Security readout for executives and security teams
Plain-English summary
Pandora FMS v756 and below has a cross-site scripting issue in the module massive operation name field. A successful attack could make script run in a user's browser, but the CVSS data indicates high privileges and user interaction are required, limiting immediate business urgency.
Executive priority
Treat this as a targeted administrative-console risk, not an internet-wide emergency. Prioritize remediation if Pandora FMS is used for critical monitoring or has broad privileged access.
Technical view
CVE-2021-46681 is CWE-79 XSS affecting Artica PFMS Pandora FMS v756 and below. The reported injection point is the module massive operation name field. CVSS 3.1 is 4.0 with AV:L/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:L.
Likely exposure
Exposure is likely limited to organizations running Pandora FMS v756 or below, especially where privileged users can access module massive operations. The source bundle does not identify other products, deployment modes, or vulnerable configurations.
Exploitation context
The bundle does not show CISA KEV listing or public evidence of active exploitation. The CVSS vector indicates exploitation requires high privileges and user interaction, with low confidentiality, integrity, and availability impact.
Researcher notes
Evidence is limited to the CVE description, CVSS vector, affected version statement, and references. No exploit status, patch version, or detailed advisory text is included in the source bundle.
Mitigation direction
- Inventory Pandora FMS deployments and identify versions v756 or below.
- Check Pandora FMS vendor guidance for the fixed release or supported remediation.
- Restrict Pandora FMS administrative access to trusted users and networks.
- Review privileged account assignments and remove unnecessary high-privilege access.
- Monitor vendor and INCIBE advisories for updated remediation details.
Validation and detection
- Confirm deployed Pandora FMS versions against the affected v756-or-below range.
- Review whether module massive operation names are safely encoded when displayed.
- Check audit logs for unusual changes to module massive operation names.
- Verify remediation against vendor guidance before closing the finding.

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.
