Summary

Cisco NX-OS Software releases are affected by a flaw in the Python interpreter. Insufficient validation of user-supplied input (CWE-653) lets an authenticated local attacker with low privileges escape the Python sandbox and run arbitrary commands on the underlying operating system with that user's privileges.

Written with Claude Haiku 5.5 from the sources below · 2026-10-29

Description from the CNA

A vulnerability in the Python interpreter of Cisco NX-OS Software could allow an authenticated, local attacker with low privileges to escape the Python sandbox and gain unauthorized access to the underlying operating system of an affected device. This 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.
