Technical description

The com.ibm.rmi.io.SunSerializableFactory class in IBM SDK, Java Technology Edition 6 before SR16 FP25 (6.0.16.25), 6 R1 before SR8 FP25 (6.1.8.25), 7 before SR9 FP40 (7.0.9.40), 7 R1 before SR3 FP40 (7.1.3.40), and 8 before SR3 (8.0.3.0) does not properly deserialize classes in an AccessController doPrivileged block, which allows remote attackers to bypass a sandbox protection mechanism and execute arbitrary code as demonstrated by the readValue method of the com.ibm.rmi.io.ValueHandlerPool.ValueHandlerSingleton class, which implements the javax.rmi.CORBA.ValueHandler interface. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-5456.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
