IBM WebSphere eXtreme Scale 8.6.1.0 < 8.6.1.6 (7278346)

medium Nessus Plugin ID 323711

Synopsis

The remote web application server is affected by a vulnerability

Description

The version of IBM WebSphere eXtreme Scale installed on the remote host is prior to 8.6.1.6 IBM. It is, therefore, affected by a vulnerability as referenced in the 7278346 advisory.

 - IBM WebSphere eXtreme Scale could allow an adjacent attacker to cause a denial of service due to improper validation in the XDF decoder. The application processes deeply nested Protocol Buffers messages and attacker-controlled length prefixes without sufficient bounds checking, which may allow an attacker on the same network to trigger a StackOverflowError or OutOfMemoryError, resulting in a crash of the WebSphere Application Server JVM. CWE: CWE-400: Uncontrolled Resource Consumption (CVE-2026-9002)

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

Solution

Please see vendor advisory for details.
