Cisco IDS/IPS Web interface SSL denial of service
|cisco-ips-ssl-dos (29056)||Medium Risk|
Multiple versions of Cisco Intrusion Prevention System (IPS) are vulnerable to a denial of service in the Web management interface. A remote attacker could send a specially-crafted SSLv2 Hello packet to an affected Web interface to cause the mainAPP process to crash, which would result in a denial of service against the management interface.
