A security vulnerability exists in the IBM Java SDK that is shipped with IBM WebSphere Application Server included with Rational Developer for System z.
The IBM WebSphere Application Server shipped in Rational Developer for System z Software includes an IBM Java SDK that is based on the Oracle JDK. Oracle has released June 2013 critical patch updates (CPU) which contain security vulnerability fixes and the IBM Java SDK has been updated to incorporate those updates.
DESCRIPTION: HTML documentation generated by the Javadoc tool contains a security vulnerability. The vulnerability allows an attacker to craft a malicious link to the documentation which injects arbitrary content into the main frame. The injected content appears to originate from the site hosting the documentation, but in fact it is hosted elsewhere, and may contain malicious links or content. This type of attack is known as "clickjacking".
The attack does not require authentication and may be exploited remotely if the html page is network available, but some degree of specialized knowledge and techniques are required. An exploit would not impact the confidentiality of information or the availability of the system, but data integrity could be compromised.
CVSS Base Score: 4.3
