Security Bulletin: Potential security vulnerability in WebSphere Application Server CVE-2013-1768 PM86780

Flash (Alert)


Potential security vulnerability in WebSphere Application Server



CVE ID: CVE-2013-1768 (PM86780, PM86786, PM86788 and PM86791)

Deserialization of a maliciously crafted OpenJPA object can result in an executable file being written to the file system. An attacker needs to discover an unprotected server program to exploit this vulnerability. It then needs to exploit another unprotected server program to execute the file and gain access to the system. OpenJPA usage by itself does not introduce the vulnerability. The OpenJPA code ships with the WebSphere Application Server but WebSphere Application Server is NOT vulnerable to this issue. We recommend installing this fix or upgrading to a fix pack that contains this code as a proactive safeguard to ensure your environment is as secure as possible.


CVSS Base Score:10
