Official Description
The Site Editor (aka SiteBuilder) feature in Parallels Plesk Small Business Panel 10.2.0 does not include the HTTPOnly flag in a Set-Cookie header for a cookie, which makes it easier for remote attackers to obtain potentially sensitive information via script access to this cookie, as demonstrated by cookies used by Wizard/Edit/Modules/ImageGallery/MultiImagesUpload and certain other files.
Technical Analysis
CVE-2011-4765 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
