Exposure of Sensitive Information to an Unauthorized Actor
The Control Panel in Parallels Plesk Panel 10.2.0 build 20110407.20 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 get_password.php and certain other files.
CWE-200 - Information Exposure
An information exposure vulnerability is categorized as an information flow (IF) weakness, which can potentially allow unauthorized access to otherwise classified information in the application, such as confidential personal information (demographics, financials, health records, etc.), business secrets, and the application's internal environment.
