An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. 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.\r\nNote: To exploit this vulnerability, Web Access must be enabled on the phone and the attacker must have Admin credentials on the device.
