Systems Affected

  • JavaFX 2.2.21 and earlier

Threat Level

Overview


Oracle released the June 2013 Critical Patch Update for Oracle Java SE. This patch contains 40 new security fixes across Java SE products and a fix to the Javadoc Tool. API documentation in HTML format generated by the Javadoc tool that contains a right frame may be vulnerable to frame injection when hosted on a web server.


Description


Oracle's June Critical Patch Update includes a fix to the Javadoc Tool. API documentation in HTML format generated by the Javadoc tool that contains a right frame may be vulnerable to frame injection when hosted on a web server. Additional information can be found in CERT Vulnerability Report VU#225657. It is recommended that sites hosting such pages should re-generate the API documentation using the latest Javadoc tool and replace the current pages with the re-generated Javadoc output. In cases where regenerating API documentation is not feasible, a Java API Documentation Updater Tool that updates API documentation "in place" is available Oracle's Java SE Downloads page.


Impact


An attacker can cause one of the frames within a Javadoc-generated web page to be replaced with a malicious page. This vulnerability could be used for phishing or social engineering, or it could be used for browser exploitation if combined with another browser-related vulnerability.


Solution/ Workarounds


Apply updates Oracle has released the June 2013 Java Critical Patch Update to address this vulnerability. Oracle Java Development Toolkit (JDK) and Javadoc users are advised to apply the June 2013 Java Critical Patch Update and regenerate and republish affected Javadoc HTML pages.
