Ivanti Cloud Services Appliance OS Command Injection
CVE-2024-8190 is a high-severity improper neutralization of special elements used in an OS command vulnerability in CSA (Cloud Services Appliance) from Ivanti, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. CISA added it to the Known Exploited Vulnerabilities catalogue on September 13, 2024, which means attacks have been observed in the wild.
Attackers are already exploiting this vulnerability, according to CISA.
What to do
- Update endpoint_manager_cloud_services_appliance to 5.0 or a later version.
- CISA's required action: As Ivanti CSA has reached End-of-Life status, users are urged to remove CSA 4.6.x from service or upgrade to the 5.0.x line of supported solutions, as future vulnerabilities on the 4.6.x version of CSA are unlikely to receive future security updates.
- Read the advisory on forums.ivanti.com for workarounds and exact fixed builds.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
