CVE-2024-8190: An OS Command Injection Vulnerability in Ivanti CSA: What You Need to Know

Image
Overview: CVE-2024-8190 is an OS command injection vulnerability found in Ivanti Cloud Services Appliance (CSA) versions 4.6 (before Patch 519) and earlier. The flaw allows a remote authenticated attacker with admin-level privileges to execute arbitrary code on the affected system. Attack Scenario: The attacker must first log into the CSA’s admin login page. While this initial login may seem like a hurdle, it’s not insurmountable in some cases. Dual-homed CSA configurations (where eth0 serves as an internal network) are less vulnerable, as recommended by Ivanti. However, not everyone follows these best practices. Users who accidentally misconfigure interfaces or have weak passwords are at risk. For instance, if an admin swaps the interfaces or configures only one interface, the CSA console could be exposed to the internet. Default login credentials (username: admin, password: admin) should be changed upon initial login. However, weak passwords and the lack of rate limiting for login at...
