Manager and IBM Tivoli Federated Identity Manager Business Gateway, caused by
improper validation of user-supplied input.
Vulnerability Details
CVEID: CVE-2015-1966
DESCRIPTION: IBM Tivoli Federated Identity Manager and IBM Security Access
Manager for Mobile are vulnerable to cross-site scripting, caused by improper
validation of user-supplied input. A remote attacker could exploit this
vulnerability using a specially-crafted URL to execute script in a victim's
Web browser within the security context of the hosting Web site, once the URL
is clicked. An attacker could use this vulnerability to steal the victim's
cookie-based authentication credentials.

Workarounds and Mitigations
To remediate this, add the following macros to the list of comma-separated
tokens in the runtime custom property SPS.PageFactory.HtmlEscapedTokens. Add
these macros so that their values are HTML-escaped in the template files.
@ERROR_DESCRIPTION@
@TOKEN:RelayState@
The value of the runtime custom property SPS.PageFactory.HtmlEscapedTokens
with the above macros added can be:
@REQ_ADDR@,@DETAIL@,@EXCEPTION_STACK@,@EXCEPTION_MSG@,@RESPONSE@,@TARGET@,@DETAIL@,@SAMLSTATUS@,@ERROR_DESCRIPTION@,@TOKEN:RelayState
NOTE: Other macros that are prone to cross site scripting vulnerability can
also be added to SPS.PageFactory.HtmlEscapedTokens. The value of this runtime
custom property will be revised periodically and update as needed. For more
information regarding the runtime custom property, access
http://www.ibm.com/support/knowledgecenter/SSZSXU_6.2.2.7/com.ibm.tivoli.fim.doc_6227/config/reference/CustomPropsSPS.html.
