Oracle WebLogic Server Deserialization RCE (CVE-2018-2628)

Critical Nessus Plugin ID 109429

Synopsis

The remote Oracle WebLogic server is affected by a remote code
execution vulnerability.

Description

The remote Oracle WebLogic server is affected by a remote code
execution vulnerability in the Core Components subcomponent due to
unsafe deserialization of Java objects by the RMI registry. An
unauthenticated, remote attacker can exploit this, via a crafted Java
object, to execute arbitrary Java code in the context of the WebLogic
server.

Note that this plugin does not attempt to exploit this RCE directly
and instead checks for the presence of the patch Oracle supplied
in the April 2018 critical patch update (CPU).

Solution

Apply the appropriate patch according to the April 2018 Oracle
Critical Patch Update advisory.

Note that the patch for CVE-2018-2628 is reportedly incomplete.
Refer to Oracle for any additional patch instructions or
mitigation options.
