CVE-2025-20196

A vulnerability in the Cisco IOx application hosting environment of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the Cisco IOx application hosting environment to stop responding, resulting in a denial of service (DoS) condition.

This vulnerability is due to the improper handling of HTTP requests. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to cause the Cisco IOx application hosting environment to stop responding. The IOx process will need to be manually restarted to recover services.
