Vulnerability from cvelistv5 – Published: 2020-05-06 16:41 – Updated: 2024-11-15 17:24

Title

Cisco Umbrella Carriage Return Line Feed Injection Vulnerability

Summary

A vulnerability in the web server of Cisco Umbrella could allow an unauthenticated, remote attacker to perform a carriage return line feed (CRLF) injection attack against a user of an affected service. The vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user to access a crafted URL. A successful exploit could allow the attacker to inject arbitrary HTTP headers into valid HTTP responses sent to the browser of the user.
