An attacker could exploit this vulnerability by sending crafted MR PIM traffic to an affected device. A successful exploit could allow the attacker to trigger a failure on the MR PIM connection between Cisco ECE and Cisco Unified Contact Center Enterprise (CCE), leading to a DoS condition on EAAS that would prevent customers from starting chat, callback, or delayed callback sessions. Note: When the attack traffic stops, the EAAS process must be manually restarted to restore normal operation. To restart the process in the System Console, choose Shared Resources > Services > Unified CCE > EAAS, then click Start.", "affected": [ { "vendor": "Cisco", "product": "Cisco Enterprise Chat and Email", "defaultStatus": "unknown", "versions": [ { "version": "11.6(1)_ES3", "status": "affected" }, { "version": "11.6(1)_ES4", "status": "affected" }, { "version": "12.0(1)_ES6", "status": "affected" }, { "version": "11.6(1)_ES9", "status": "affected" }, { "version": "11.6(1)_ES6", "status": "affected" }, { "version": "11.6(1)_ES5", "status": "affected" }, { "version": "12.5(1)_ET1", "status": "affected" }, { "version": "12.5(1)_ES3_ET1", "status": "affected" }, { "version": "12.0(1)_ES3", "status": "affected" }, { "version": "11.6(1)_ES11", "status": "affected" }, { "version": "12.0(1)_ES4", "status": "affected" }, { "version": "12.0(1)_ES5", "status": "affected" }, { "version": "11.6(1)_ES2", "status": "affected" }, { "version": "11.6(1)_ES9a", "status": "affected" }, { "version": "11.6(1)_ES10", "status": "affected" }, { "version": "12.0(1)_ES1", "status": "affected" }, { "version": "12.0(1)", "status": "affected" }, { "version": "12.5(1)_ES3", "status": "affected" }, { "version": "12.6(1)", "status": "affected" }, { "version": "11.5(1)", "status": "affected" }, { "version": "12.0(1)_ES2", "status": "affected" }, { "version": "11.6(1)_ES7", "status": "affected" }, { "version": "12.6(1)_ET1", "status": "affected" }, { "version": "11.6(1)", "status": "affected" }, { "version": "12.6(1)_ET2", "status": "affected" }, { "version": "12.5(1)_ES3_ET2", "status": "affected" }, { "version": "12.0(1)_ES6_ET2", "status": "affected" }, { "version": "12.6(1)_ES1", "status": "affected" }, { "version": "11.6(1)_ES12", "status": "affected" }, { "version": "12.6(1)_ET3", "status": "affected" }, { "version": "12.5(1)_ES4_ET1", "status": "affected" }, { "version": "12.0(1)_ES6_ET3", "status": "affected" }, { "version": "12.6(1)_ES1_ET1", "status": "affected" }, { "version": "12.6(1)_ES2", "status": "affected" }, { "version": "12.6_ES2_ET1", "status": "affected" }, { "version": "12.5(1)_ES5", "status": "affected" }, { "version": "12.6_ES2_ET2", "status": "affected" }, { "version": "12.0(1)_ES7", "status": "affected" }, { "version": "12.6_ES2_ET3", "status": "affected" }, { "version": "12.0(1)_ES7_ET1", "status": "affected" }, { "version": "12.5(1)_ES5_ET1", "status": "affected" }, { "version": "12.6_ES2_ET4", "status": "affected" }, { "version": "12.6(1)_ES3", "status": "affected" }, { "version": "11.6(1)_ES12_ET1", "status": "affected" }, { "version": "12.6_ES3_ET1", "status": "affected" }, { "version": "12.6_ES3_ET2", "status": "affected" }, { "version": "12.6(1)_ES4", "status": "affected" }, { "version": "12.5(1)_ES7", "status": "affected" }, { "version": "12.6(1)_ES4_ET1", "status": "affected" }, { "version": "12.6(1)_ES5", "status": "affected" }, { "version": "12.6(1)_ES5_ET1", "status": "affected" }, { "version": "12.6(1)_ES5_ET2", "status": "affected" }, { "version": "12.6(1)_ES6", "status": "affected" }, { "version": "12.6(1)_ES6_ET1", "status": "affected" }, { "version": "12.5(1)_ES8", "status": "affected" }, { "version": "12.6(1)_ES6_ET2", "status": "affected" }, { "version": "12.6(1)_ES7", "status": "affected" }, { "version": "12.6(1)_ES8", "status": "affected" }, { "version": "12.6(1)_ES4_ET2", "status": "affected" }, { "version": "12.6(1)_ES3_ET3", "status": "affected" }, { "version": "12.6(1)_ES2_ET5", "status": "affected" }, { "version": "12.6(1)_ES1_ET2", "status": "affected" }, { "version": "12.6(1)_ES8_ET1", "status": "affected" }, { "version": "12.6(1)_ES7_ET1", "status": "affected" }, { "version": "12.6(1)_ES6_ET3", "status": "affected" }, { "version": "12.6(1)_ES5_ET3", "status": "affected" }, { "version": "12.5(1)_ES8_ET1", "status": "affected" }, { "version": "12.5(1)_ES3_ET3", "status": "affected" }, { "version": "12.5(1)_ES5_ET2", "status": "affected" }, { "version": "12.5(1)_ES6_ET1", "status": "affected" }, { "version": "12.5(1)_ES4_ET2", "status": "affected" }, { "version": "12.5(1)_ES7_ET1", "status": "affected" }, { "version": "12.6(1)_ES8_ET2", "status": "affected" }, { "version": "12.6(1)_ES9", "status": "affected" }, { "version": "12.6(1)_ES9_ET1", "status": "affected" } ] } ] } } }
