"The Pulse Connect Secure installed on the remote host is prior to 22.7R2.3. It is, therefore, affected by 
multiple vulnerabilities.

- A heap-based buffer overflow in IPsec of Ivanti Connect Secure before version 22.7R2.3 allows a remote 
  unauthenticated attacker to cause a denial of service. (CVE-2024-37377)

- Command injection in Ivanti Connect Secure before version 22.7R2.3 and Ivanti Policy Secure allows a remote 
  authenticated attacker with admin privileges to achieve remote code (CVE-2024-11634)

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