Plesk PHP vulnerability

Last UpdateSat, 5 May 2012 03:38 AM UTC (372 weeks ago)

An open source PHP security vulnerability was identified that impacts some of Parallels products.

Situation: The PHP Group and the United States Computer Emergency Readiness Team (US-CERT) issued a vulnerability alert on 3 May that PHP-CGI-based setups contain vulnerability when parsing query string parameters from PHP files. You can find more information at the PHP's website. A permanent solution has not been provided by the Open Source PHP community as of 5 pm PDT on May 4, 2012.

Impact: A remote unauthenticated attacker could obtain sensitive information, cause a denial of service condition or may be able to execute arbitrary code with the privileges of the web server.

Products Impacted: Parallels Plesk Panel for Linux versions 9.0 - 9.2.3 only

Solution: As per the Parallels Plesk Lifecycle Policy, these versions do not provide ongoing patch support. Having customers upgrade to the latest version of Parallels Plesk Panel will eliminate this vulnerability.

Parallels understands that it's not always practical for immediate upgrades, so we have provided a solution to fix this vulnerability. For the immediate solution, customers should read this knowledge base article for instructions: http://kb.parallels.com/en/113818

Most of our users with plesk 9.* should have already updated to 9.5. But if you do need any help in updating the Plesk Panel please raise a ticket at https://rimuhosting.com/ticket/startticket.jsp and we can help get that sorted for you.
