Security Bulletin: Potential Security Vulnerability in the WebSphere
Application Server Admin Console (CVE-2017-1501)


Document information

More support for: IBM Campaign 3rd Party Configuration
Software version: 8.0, 8.5, 9.0
Operating system(s): AIX, Linux, Solaris, Windows
Software edition: Enterprise
Reference #: 2013862
Modified date: 21 February 2018


Summary

There is a potential security vulnerability in the WebSphere Application Server
Admin Console, if you have updated the web services security bindings settings.
If you changed the cipher suites in the web services security bindings settings
they may not have been saved properly and thus have weaker security then you
expected. Verify that your settings are what you expect.

Vulnerability Details

CVEID: CVE-2017-1501
DESCRIPTION: IBM WebSphere Application Server could provide weaker than
expected security after using the Admin Console to update the web services
security bindings settings.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
129576 for the current score

Affected Products and Versions

WebSphere Application Server Version 8.0, Version 8.5, Version 9.0

Remediation/Fixes

If you have recently changed the cipher suites in the web services security
binding settings they may not have been saved properly. This only happened for
a few fixpack releases. Verify that your settings are what you expect. If you
are using any of the affected fixpack levels 9.0.0.0 - 9.0.0.4, 8.5.5.10,
8.5.5.11 or 8.0.0.13 then the recommended solution is to apply the interim fix,
Fix Pack or PTF containing APAR PI80889 for each named product as soon as
practical to ensure the web services security bindings settings will get saved
properly in the future.

For WebSphere Application Server traditional and WebSphere Application Server
Hypervisor Edition:
For V9.0.0.0 through 9.0.0.4:
- - Apply Interim Fix PI80889
- --OR--
- - Apply Fix Pack 9.0.0.5 or later.

For V8.5.5.10 through 8.5.5.11:
- - Apply Interim Fix PI80889      
- --OR--
- - Apply Fix Pack 8.5.5.12 or later.

For V8.0.0.13:
- - Apply Interim Fix PI80889

- --OR--
