affected by mutliple vulnerabilities: 

  - An unspecified SQL injection in Ivanti EPM before the 2024 September update allows a remote 
    authenticated attacker with admin privileges to achieve remote code execution. (CVE-2024-32840)

  - An unspecified SQL injection in Ivanti EPM before the 2024 September update allows a remote 
    authenticated attacker with admin privileges to achieve remote code execution. (CVE-2024-32843)
  
  - An unspecified SQL injection in Ivanti EPM before the 2024 September update allows a remote

Note that Nessus has not tested for these issues but has instead relied only on the 
service's self-reported version number of the affected dll files.");
