Synopsis :

The remote device is running a vulnerable version of NX-OS.

Description :

According to its self-reported version, the remote NX-OS device is
reportedly affected by one or more of the following vulnerabilities :

- A privilege escalation flaw exists on systems with
multiple virtual device contexts (VDCs) and local
authentication configured. This could allow a
remote, authenticated attacker to gain the privileges
of an administrator in another VDC. Affects Nexus 7000
series devices. (CVE-2013-1191)

- A privilege escalation flaw exists on systems with
multiple virtual device contexts (VDCs) and local
authentication configured. This could allow a
remote, authenticated attacker to gain the privileges
of an administrator in another VDC. Affects Nexus 7000
series devices. (CVE-2014-2200).

- A buffer overflow flaw exists with the Smart Call Home
feature. A remote attacker, with control of a
configured SMTP server, could execute arbitrary code
with elevated privileges. (CVE-2014-3261)

- A denial of service flaw exists with the Message
Transfer Service (MTS) due to a NULL pointer
dereference. This could allow a remote attacker to
trigger a denial of service. Note that Cisco has
investigated the issue, and has found that no official
releases are affected. Only pre-release versions of
NX-OS 6.0 are affected. (CVE-2014-2201)
