Detailsinfo

A vulnerability was found in Cisco NX-OS on Nexus 7000 (Router Operating System) (the affected version unknown). It has been rated as critical. Affected by this issue is an unknown part of the component Message Transfer Service. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. CVE summarizes:

The Message Transfer Service (MTS) in Cisco NX-OS before 6.2(7) on MDS 9000 devices and 6.0 before 6.0(2) on Nexus 7000 devices allows remote attackers to cause a denial of service (NULL pointer dereference and kernel panic) via a large volume of crafted traffic, aka Bug ID CSCtw98915.

The weakness was published 05/21/2014 with Cisco as cisco-sa-20140521-nxos / CSCtw98915 as confirmed advisory (Website). The advisory is available at tools.cisco.com.

The technical details are unknown and an exploit is not available. The advisory points out:

Cisco NX-OS-Based products that support the Smart Call Home feature set are affected by a buffer overflow vulnerability. An unauthenticated, remote attacker who can obtain control of a configured SMTP server could trigger a buffer overflow condition. Successful exploitation could allow the attacker to execute arbitrary code with elevated privileges on the affected device. This vulnerability is due to a failure to properly sanitize input received from remote hosts while sending a Smart Call Home notification.
