This mechanism is vulnerable to cross-site scripting attacks. Vulnerability Details CVE ID: CVE-2014-6101 DESCRIPTION: IBM Business Process Manager is vulnerable to cross-site scripting, which is caused by the improper validation of user-supplied input. A remote attacker might exploit this vulnerability using a specially crafted URL to execute a script in a user's web browser within the security context of the hosting web site after the URL is clicked. An attacker might use this vulnerability to steal the user's cookie-based authentication credentials. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/96024 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N) Affected Products and Versions IBM Business Process Manager Standard V7.5.x, 8.0.x 8.5.x IBM Business Process Manager Express V7.5.x, 8.0.x 8.5.x IBM Business Process Manager Advanced V7.5.x, 8.0.x 8.5.x Remediation/Fixes Install the interim fix for APAR JR51211 as appropriate for your current IBM Business Process Manager version. Note: IBM Business Process Manager V7.5 and 8.0 require a second interim fix: JR51507 Interim Fixes for APAR JR51211 IBM Business Process Manager Express IBM Business Process Manager Standard IBM Business Process Manager Advanced Interim Fixes for APAR JR51507 IBM Business Process Manager Express IBM Business Process Manager Standard IBM Business Process Manager Advanced Workarounds and Mitigations The attack requires a user to access a malicious URL that the attacker has constructed for this purpose. Advise your users not to click links of unknown or untrusted origins.
