CVE-2011-4854: Parallels Plesk Panel

High severity, CVSS 9.3. EPSS: 1.6% chance of exploitation in the next 30 days.

The Control Panel in Parallels Plesk Panel 10.4.4_build20111103.18 does not ensure that Content-Type HTTP headers match the corresponding Content-Type data in HTML META elements, which might allow remote attackers to have an unspecified impact by leveraging an interpretation conflict involving the get_enabled_product_icon program. NOTE: it is possible that only clients, not the Plesk product, could be affected by this issue.
