The Control Panel in Parallels Plesk Panel 10.2.0 build 20110407.20 sends incorrect Content-Type headers for certain resources, which might allow remote attackers to have an unspecified impact by leveraging an interpretation conflict involving smb/admin-home/featured-applications/ and certain other files. NOTE: it is possible that only clients, not the Plesk product, could be affected by this issue.

Analyst readout for executives and security teams

Plain-English summary

This is an old Plesk Control Panel issue where version 10.2.0 build 20110407.20 may serve some resources with incorrect Content-Type headers. That can cause clients to interpret content differently than intended. The public record does not define the impact or confirm the server itself is affected.

Executive priority

Treat this as a legacy-technology exposure check, not a confirmed emergency. The main business concern is unsupported or internet-exposed Plesk administration, because the CVE impact is unclear and no active exploitation evidence is provided.

Technical view

CVE-2011-4744 describes incorrect Content-Type headers for resources under smb/admin-home/featured-applications/ and other files in Parallels Plesk Panel 10.2.0 build 20110407.20. The issue is framed as an interpretation conflict with unspecified impact, and the CVE note says only clients may be affected.

Likely exposure

Exposure appears limited to environments still running Parallels Plesk Panel 10.2.0 build 20110407.20 or closely related deployed resources. The source bundle does not provide confirmed CPEs, affected version ranges, or supported-product mappings.

Exploitation context

The provided sources do not show CISA KEV listing, active exploitation, exploit maturity, or real-world incident use. One reference title mentions reflected XSS, but the CVE record itself only states incorrect headers and unspecified impact.

Researcher notes

The record lacks CVSS, CWE, CPEs, concrete impact, and vendor remediation details. Preserve the distinction between incorrect server headers and possible client-side interpretation risk. Do not infer affected versions beyond Plesk Panel 10.2.0 build 20110407.20 from the provided bundle.

Mitigation direction

  • Identify whether any Plesk instance matches version 10.2.0 build 20110407.20.
  • Check current vendor guidance for supported upgrades or advisories.
  • Restrict administrative panel exposure to trusted networks where operationally possible.
  • Review reverse proxy or security header controls without assuming they fully remediate.
  • Prioritize migration from unsupported legacy Plesk versions.

Validation and detection

  • Confirm deployed Plesk version and build from asset inventory.
  • Review HTTP response headers for affected Plesk panel resources.
  • Check whether administrative interfaces are internet-accessible.
  • Search vulnerability management data for CVE-2011-4744 findings.
  • Document uncertainty where scanner evidence lacks version confirmation.
