Cisco IMC Change Password Authentication Bypass
CVE-2026-20093 is a critical authentication bypass vulnerability in the change password functionality of Cisco Integrated Management Controller (IMC). The flaw is caused by incorrect handling of password change requests. An unauthenticated remote attacker can exploit the issue by sending a crafted HTTP request to an affected IMC interface, allowing the attacker to bypass authentication checks and modify the password of any existing account on the system, including the Admin account. After changing the target account's password, the attacker can log in as that user and obtain corresponding privileges. Cisco assigned CVSS v3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H and a base score of 9.8.
