CVE-2011-4768: Parallels Plesk Small Business Panel

High severity, CVSS 10.0. EPSS: 1.9% chance of exploitation in the next 30 days.

The Site Editor (aka SiteBuilder) feature in Parallels Plesk Small Business Panel 10.2.0 omits the Content-Type header's charset parameter for certain resources, which might allow remote attackers to have an unspecified impact by leveraging an interpretation conflict involving Wizard/Edit/Modules/Image and certain other files. NOTE: it is possible that only clients, not the Plesk product, could be affected by this issue.

Affected products

• Parallels Parallels Plesk Small Business Panel: version 10.2.0 only
