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.

CVSS Base Score: 4.3

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.
