Cisco voice products installed on IBM servers denial of service
| ciscovoice-ibmservers-dos (14901) |  Low Risk |
Description:
Multiple Cisco products running on IBM servers are vulnerable to a denial of service attack. The default installation of multiple Cisco voice products on certain IBM servers running operating systems prior to OS 2000.2.6 installs the IBM Director while leaving 14247 open. A remote attacker can exploit this vulnerability to consume 100% of the available CPU resources. The server must be restarted to gain normal functionality.
