Summary

A fix is available for an Open Redirect Vulnerability in IBM WebSphere Portal
(CVE-2018-1736).

Vulnerability Details

CVEID: CVE-2018-1736
DESCRIPTION: IBM WebSphere Portal could allow a remote attacker to conduct
phishing attacks, using an open redirect attack. By persuading a victim to
visit a specially-crafted Web site, a remote attacker could exploit this
vulnerability to spoof the URL displayed to redirect a user to a malicious Web
site that would appear to be trusted. This could allow the attacker to obtain
highly sensitive information or conduct further attacks against the victim.

Note: PH01459 introduces a configurable white list for external hosts, which
are allowed as redirects via the CategoryProfileUpdater Module. Server relative
redirects are continuously working. Redirects to external hosts not specified

|                                                      |only certain hosts.   |
|                                                      |The list is a         |

+------------------------------------------------------+----------------------+

Example:
categoryProfileUpdaterModule.redirectURL.restrictHosts=true
categoryProfileUpdaterModule.redirectURL.allowedHosts=www.ibm.com

Having these set would only allow the redirect URL to be to arbitrary urls at
the www.ibm.com host (E.g. http://www.ibm.com/, https://www.ibm.com/us-en/).

If redirects are blocked, a message containing the URL can be found in the log:

"The redirect URL '<REDIRECT_URL>' for the CategoryProfileUpdater Module is
unauthorized and has been blocked. To configure a whitelist of permitted hosts
for the redirect URL use WCMConfigService property
categoryProfileUpdaterModule.redirectURL.allowedHosts, or temporarily disable
(not recommended) using categoryProfileUpdaterModule.redirectURL.restrictHosts=
false. See PH01459 / CVE-2018-1736."

Based on this message you need to decide, whether to enhance the white list for
a valid scenario or leave it blocked.

Workarounds and Mitigations

Prior to the fixed Cumulative Fix versions as listed in the "Remediation/
Fixes", the installation of a Combined Cumulative Fix (CF) resets access
control settings for the IBM WebSphere Portal out of the box resources. The out
of the box access control settings are restored for them. If the access control
settings of these out of the box resources had been changed before, you need to
set them again to their customized values after Cumulative Fix installation.

See the IBM Knowledge center how to manage the access control and get an
overview of initial access control settings.
