This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. ## Affected - `unified_communications_manager_im_and_presence_service >= 15.0, < 15su3` - `unified_communications_manager_im_and_presence_service = 12.5` - `unified_communications_manager_im_and_presence_service = 14.0` ## Remediation Upgrade past the affected range: - `unified_communications_manager_im_and_presence_service 15su3`
