IBM WebSphere Application Server 8.5.x < 8.5.5.18 / 9.0.x < 9.0.5.5 RCE (CVE-2020-4450)

critical Nessus Plugin ID 137368

Language:

Synopsis

The remote web application server is affected by a remote code execution vulnerability

Description

The IBM WebSphere Application Server running on the remote host is version 8.5.x prior to 8.5.5.18 or 9.0.x prior to 9.0.5.5. It is, therefore, affected by a remote code execution vulnerability. A remote, unauthenticated attacker can exploit this by sending a specially-crafted sequence of serialized objects in order to execute arbitrary code on the affected system.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to IBM WebSphere Application Server 8.5.5.18, 9.0.5.5, or later. Alternatively, upgrade to the minimal fix pack levels required by the interim fix and then apply Interim Fix PH25074.
