CVE-2016-5756

Situation

Access Manager setup and working well. As part of a security test, a PEN test was carried out against all NAM components and many iManager URLs were prone to Reflected Cross-Site Scripting attacks. This Cross-Site Scripting vulnerability allows an attacker to send a manipulated link to his victim in order to execute arbitrary JavaScript code in the context of his victim’s web browser. As a result, it is possible to steal cookie information in order to hijack user sessions. Another possibility is to load other malicious code.

• /nps/servlet/frameservice parameter: taskId
• /nps/servlet/webacc perameter: SelectedAttribute
• /nps/servlet/webacc perameter: User.context
• /nps/servlet/webacc perameter: callBack
• /nps/servlet/webacc perameter: controlName

• /roma/jsp/admin/appliance/devicedetail_edit.jsp perameter: focus
• /roma/jsp/admin/managementip/mgmt_ip_details_frameset.jsp perameter: managementip
• /roma/jsp/admin/managementip/mgmt_ip_details_middleframe.jsp perameter: managementip
• /roma/jsp/volsc/monitoring/appliance.jsp perameter: appname
