Known Affected Releases


Description (partial)

The Cisco NX-OS software contains a directory traversal vulnerability within the command line interface that could allow a local, authenticated attacker to disclose the contents of arbitrary files on the affected device.  An attacker could leverage the NX-OS ''copy'' command to duplicate the contents of arbitrary files on the device to a user writable area of the filesystem.  As the new file will be owned by the authenticated user, the attacker will be able to view the contents.

This vulnerability affects the following platforms which are based on Cisco NX-OS:

Cisco Nexus 9000
Cisco Nexus 7000
Cisco Nexus 6000
Cisco Nexus 5500
Cisco Nexus 5000
Cisco Nexus 4000
Cisco Nexus 3500
Cisco Nexus 3000
Cisco Nexus 1000V
Cisco MDS 9000
Cisco Connected Grid Router 1000 Series
Cisco Unified Computing System Fabric Interconnect 6200
Cisco Unified Computing System Fabric Interconnect 6100

Device is running an affected version of Cisco NX-OS software, and an authenticated user with the privileges to run the copy command.
