Security readout for executives and security teams

Plain-English summary

Centreon-Web 20.10.0 has a stored XSS issue in the Hosts configuration area. An authenticated user can place script or HTML in a host Alias field, potentially affecting other users who later view that content. The sources do not provide CVSS, confirmed exploitation, or a named fixed version.

Executive priority

Handle as a near-term remediation item, especially for internet-accessible or broadly administered Centreon environments. It is not currently evidenced as actively exploited in the supplied sources, but stored XSS in a monitoring platform can affect administrator trust and operational integrity.

Technical view

CVE-2021-28054 is a stored cross-site scripting vulnerability in Centreon-Web within Centreon Platform 20.10.0. The described injection point is the Alias parameter under Configuration > Hosts. The source bundle identifies remote authenticated users as the attacker class but does not provide CWE, CVSS, or detailed remediation data.

Likely exposure

Exposure is most likely where Centreon Platform 20.10.0 is deployed and authenticated users can create or edit host configuration Alias values. The provided affected-product metadata is incomplete, so teams should verify against Centreon inventory and vendor release guidance.

Exploitation context

The source bundle does not cite active exploitation, and CISA KEV status is false. Exploitation requires authenticated access. Stored XSS can create business risk when lower-privileged or compromised accounts can alter content later viewed by administrators or operators.

Researcher notes

Evidence is limited to the CVE description and references. The bundle names Centreon Platform 20.10.0 and the Alias parameter, but does not include CVSS, CWE, proof-of-concept status, affected CPEs, or an explicit fixed version. Avoid expanding scope without vendor confirmation.

Mitigation direction

  • Check Centreon guidance and release notes for confirmed fixed versions.
  • Restrict host configuration privileges to trusted administrative users.
  • Review existing Host Alias values for unexpected HTML or script content.
  • Upgrade affected deployments when vendor-supported remediation is confirmed.
  • Monitor for suspicious or unauthorized host configuration changes.

Validation and detection

  • Identify any Centreon Platform 20.10.0 deployments.
  • Confirm whether Centreon-Web is present in those environments.
  • Review who can edit Configuration > Hosts Alias values.
  • Inspect Host Alias fields for unexpected markup or script-like content.
  • Check change history or logs for unusual host configuration edits.
