The Control Panel in Parallels Plesk Panel 10.4.4_build20111103.18 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 admin/customer-service-plan/list/reset-search/true/ and certain other files. NOTE: it is possible that only clients, not the Plesk product, could be affected by this issue.

The Control Panel in Parallels Plesk Panel 10.4.4_build20111103.18 does not set the secure flag for a cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session, as demonstrated by cookies used by help.php and certain other files.
