IBM WebSphere Application Server 8.0.0.x <= 184.108.40.206 / 8.5.x < 220.127.116.11 / 9.0.0.x < 18.104.22.168 Installation Verification Tool Cross-site Scripting (XSS) Vulnerability (CVE-2018-1643)
Medium Nessus Plugin ID 119678
SynopsisThe remote web application server is affected by a cross-site scripting vulnerability.
DescriptionThe IBM WebSphere Application Server running on the remote host is version 22.214.171.124 through 126.96.36.199, 8.5.x prior to 188.8.131.52, or 9.0.0.x prior to 184.108.40.206. It is, therefore, affected by a cross-site scripting (XSS) vulnerability due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.
SolutionUpgrade to IBM WebSphere Application Server 220.127.116.11 or 18.104.22.168 or later. Alternatively, upgrade to the minimal fix pack levels required by the interim fix and then apply Interim Fix PI98558.
