# A command injection vulnerability in web components of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure…

Ivanti Connect Secure and Policy Secure contain a command injection flaw in their web components. An attacker who holds administrator access can send crafted requests to run code on the appliance, and it is chained with CVE-2023-46805, an authentication bypass.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Ivanti Connect Secure (ICS, formerly known as Pulse Connect Secure) and Ivanti Policy Secure contain a command injection vulnerability in the web components of these products, which can allow an authenticated administrator to send crafted requests to execute code on affected appliances. This vulnerability can be leveraged in conjunction with CVE-2023-46805, an authenticated bypass issue.

CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
