IBM WebSphere Application Server Information Disclosure (6489485)

medium Nessus Plugin ID 153587
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 web application server is affected by an information disclosure vulnerability.

Description

The version of WebSphere Application Server installed on the remote host is affected by an information disclosure vulnerability that allows a remote user to enumerate usernames due to a difference of responses from valid and invalid login attempts.

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

Solution

Upgrade to IBM WebSphere Application Server 8.5.5.21, 9.0.5.10, or later. Alternatively, upgrade to the minimal fix pack levels required by the interim fix and then apply Interim Fix PH38929.
