"The Ivanti Policy Secure installed on the remote host is 9.x or 22.x. It is, therefore, affected by 
multiple vulnerabilities:

- A heap overflow vulnerability in IPSec component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure
allows an unauthenticated malicious user to send specially crafted requests in-order-to crash the service thereby
causing a DoS attack. In certain conditions this may lead to execution of arbitrary code. (CVE-2024-21894)

- A null pointer dereference vulnerability in IPSec component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy
Secure allows an unauthenticated malicious user to send specially crafted requests in-order-to crash the service
thereby causing a DoS attack. (CVE-2024-22052)

- A heap overflow vulnerability in IPSec component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure
allows an unauthenticated malicious user to send specially crafted requests in-order-to crash the service thereby
causing a DoS attack or in certain conditions read contents from memory. (CVE-2024-22053)

- An XML entity expansion or XEE vulnerability in SAML component of Ivanti Connect Secure (9.x, 22.x) and Ivanti
Policy Secure allows an unauthenticated attacker to send specially crafted XML requests in-order-to temporarily
cause resource exhaustion thereby resulting in a limited-time DoS. (CVE-2024-22023)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
