Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, Cisco NX-OS Software is affected by multiple vulnerabilities.

- A vulnerability in the Python interpreter of Cisco NX-OS Software could allow an authenticated, low- privileged, local attacker to escape the Python sandbox and gain unauthorized access to the underlying operating system of the device. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by manipulating specific functions within the Python interpreter. A successful exploit could allow an attacker to escape the Python sandbox and execute arbitrary commands on the underlying operating system with the privileges of the authenticated user.
Note: An attacker must be authenticated with Python execution privileges to exploit these vulnerabilities.
For more information regarding Python execution privileges, see product-specific documentation, such as the section of the Cisco Nexus 9000 Series NX-OS Programmability Guide. (CVE-2024-20284, CVE-2024-20285, CVE-2024-20286)
