CISA KEV Advisory
Ivanti Connect Secure and Policy Secure Command Injection Vulnerability
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.
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Risk Analysis
Ivanti Connect Secure (ICS) and Ivanti Policy Secure are vulnerable to a command injection flaw in their web components, allowing an authenticated administrator to execute code. This vulnerability can be chained with an authentication bypass (CVE-2023-46805), and the high EPSS score of 0.94412 indicates a very high likelihood of exploitation.
This vulnerability is actively exploited in the wild and is included in CISA's KEV catalog, confirming its confirmed exploitation. While requiring authentication, it can be combined with other flaws to achieve unauthenticated access.
