Cisco NX-OS Software Python Sandbox Escape Vulnerabilities
Discription

Multiple vulnerabilities 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. These vulnerabilities are due to insufficient validation of user-supplied input. An attacker could exploit these vulnerabilities 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 Cisco NX-OS Security with Python ["https://www.cisco.com/c/en/us/td/docs/dcn/nx-os/nexus9000/105x/programmability/cisco-nexus-9000-series-nx-os-programmability-guide-105x/m-n9k-python-api-101x.html?bookSearch=true#concept_A2CFF094ADCB414C983EA06AD8E9A410"] section of the Cisco Nexus 9000 Series NX-OS Programmability Guide. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
