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

critical Nessus Plugin ID 109429
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
