A vulnerability in the Stream Editor (sed) command-line filter in Cisco NX-OS Software could allow an authenticated, local attacker to read and write arbitrary files.
The vulnerability is due to an input validation issue. An attacker could exploit this vulnerability by using the sed r and sed w commands. A successful exploit could result in a complete compromise of the affected device.
Cisco has confirmed the vulnerability in a security notice and has released software updates.
To exploit this vulnerability, an attacker requires authenticated access to the targeted system. Authenticated access may require the attacker to access trusted, internal networks. These access requirements could limit the likelihood of a successful exploit.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
