Vulnerability from cvelistv5 – Published: 2019-09-25 20:16 – Updated: 2024-11-20 17:09

Title

Cisco IOS XE Software IOx Guest Shell Namespace Protection Vulnerability

Summary

A vulnerability in the filesystem of Cisco IOS XE Software could allow an authenticated, local attacker within the IOx Guest Shell to modify the namespace container protections on an affected device. The vulnerability is due to insufficient file permissions. An attacker could exploit this vulnerability by modifying files that they should not have access to. A successful exploit could allow the attacker to remove container protections and perform file actions outside the namespace of the container.

Severity
