IBM WebSphere Application Server 7.0.0.x <= 7.0.0.45 / 8.0.0.x <= 8.0.0.15 / 8.5.x < 8.5.5.16 / 9.0.0.x < 9.0.0.11 / Liberty < 19.0.0.4 Request Header Denial of Service (DoS) Vulnerability (CVE-2019-4046)

high Nessus Plugin ID 124024

Synopsis

The remote web application server is affected by a denial of service vulnerability.

Description

The IBM WebSphere Application Server running on the remote host is version 7.0.0.0 through 7.0.0.45, 8.0.0.0 through 8.0.0.15, 8.5.x prior to 8.5.5.16, 9.0.0.x prior to 9.0.0.11, or Liberty prior to 19.0.0.4. It is, therefore, affected by a denial of service (DoS) vulnerability due to improper handling of request headers. A remote, unauthenticated attacker could exploit this to cause the consumption of memory.

Solution

Upgrade to IBM WebSphere Application Server 8.5.5.16 or 9.0.0.11 or Liberty 19.0.0.4 or later. Alternatively, upgrade to the minimal fix pack levels required by the interim fix and then apply Interim Fix PH06340.
