CVE

CVE-2022-20726

TITLE

Cisco Iox Security hole

Trust: 0.6

sources: CNNVD: CNNVD-202204-3312

DESCRIPTION

Multiple vulnerabilities in the Cisco IOx application hosting environment on multiple Cisco platforms could allow an attacker to inject arbitrary commands into the underlying host operating system, execute arbitrary code on the underlying host operating system, install applications without being authenticated, or conduct a cross-site scripting (XSS) attack against a user of the affected software. For more information about these vulnerabilities, see the Details section of this advisory. Cisco Iox is a secure development environment from Cisco (Cisco) that combines Cisco IOS and Linux OS for secure network connection and development of IOT applications. A security vulnerability exists in the Cisco Iox application hosting environment that stems from insufficient error handling of socket operations. An attacker could exploit the vulnerability by sending a sustained rate of compressed TCP traffic to the IOx web server on an affected device. Successful exploitation of this vulnerability could allow an attacker to cause the IOx web server to stop processing requests, resulting in a DoS situation. The following products and versions are affected: Cisco 809 Industrial Integrated Services Routers (Industrial ISRs), Cisco 829 Industrial ISRs, Cisco CGR 1000 Compute Module, and Cisco IC3000 Industrial Compute Gateway
