CVE-2024-21887
Overview
This vulnerability is a command injection flaw rooted in improper input validation within the web components of Ivanti Connect Secure and Ivanti Policy Secure appliances. Specifically, authenticated administrator requests are insufficiently sanitized, allowing crafted input to be executed as system commands. The affected components are the web interfaces of Ivanti Connect Secure versions 9.x and 22.x and Ivanti Policy Secure versions 9.x and 22.x.
Vulnerability Description
A command injection vulnerability in web components of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure (9.x, 22.x) allows an authenticated administrator to send specially crafted requests and execute arbitrary commands on the appliance.
Impact
An attacker with administrator access can execute arbitrary system commands on the affected appliance, enabling full control over the device. This can lead to unauthorized data access, manipulation of security policies, and potential pivoting within the network. The prerequisite is possession of valid administrative credentials, which may be obtained through other means. The business impact includes compromise of the appliance integrity, disruption of secure gateway functions, and potential exposure of sensitive network traffic.
Solution
Ivanti has released security updates addressing this command injection vulnerability in Ivanti Connect Secure and Ivanti Policy Secure appliances. Administrators should apply the latest patches available for versions 9.x and 22.x as detailed in Ivanti’s security 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. Following vendor instructions for upgrading to patched firmware versions is required to remediate this issue.
