CVE-2015-6415 [MEDIUM] CWE-399 Cisco Unified Computing System 6200 Series Fabric Interconnect Series Switch DoS Vulnerability
Cisco Unified Computing System 6200 Series Fabric Interconnect Series Switch DoS Vulnerability
A vulnerability in the SSH management interface of the Cisco Unified Computing System (UCS) 6200 Series Fabric Interconnect Series Switch could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition because a fabric interconnect interface might not boot completely up or might have high CPU utilization. This would only happen if the attack occurred while a reload of the affected UCS switch was already in progress.
The vulnerability is due to a lack of rate-limiting on incoming TCP connection requests for SSH, which is TCP port 22 during boot time. An attacker could exploit this vulnerability by sending a TCP SYN flood of packets to the SSH management interface of
