CVE-2023-20231

What is CVE-2023-20231?

A vulnerability exists within the web user interface of Cisco IOS XE Software that could be exploited by an authenticated, remote attacker to perform injection attacks. The flaw arises from insufficient input validation, enabling an attacker to send specially crafted input to the web UI.
