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.

Security readout for executives and security teams

This CVE describes a legacy Plesk Control Panel cookie weakness. In Parallels Plesk Panel 10.2.0 build 20110407.20, at least one cookie was set without the HttpOnly protection, making theft of sensitive cookie data easier if an attacker can run script in the user’s browser. Exposure is most likely limited to organizations still running Parallels Plesk Panel 10.2.0 build 20110407.20 or an unremediated related deployment. Current exposure cannot be confirmed from the supplied sources alone. Treat as a legacy platform hygiene issue with moderate urgency. It is not listed as actively exploited in the supplied data, but exposed administrative panels with weak cookie protections increase account compromise risk. Mitigation focus: Identify any Plesk Control Panel 10.2.0 build 20110407.20 deployments.; Check current Plesk vendor guidance for supported upgrade or remediation paths.; Retire or upgrade unsupported legacy Plesk installations where present..
