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."}, {"lang": "es", "value": "Una vulnerabilidad en la funci\u00f3n External Agent Assignment Service (EAAS) de Cisco Enterprise Chat and Email (ECE) podr\u00eda permitir que un atacante remoto no autenticado provoque una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado.
