CVE-2011-4733: Parallels Plesk Panel

High severity, CVSS 10.0. EPSS: 1.8% chance of exploitation in the next 30 days.

The Server Administration Panel in Parallels Plesk Panel 10.2.0_build1011110331.18 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/disable-featured-applications-promo and certain other files. NOTE: it is possible that only clients, not the Plesk product, could be affected by this issue.
