"The version of N-able N-central installed on the remote host is prior to 2024.6 HF2 or 2025.x prior to 2025.3.1. It is,
therefore, affected by multiple vulnerabilities:

  - Deserialization of Untrusted Data vulnerability in N-able N-central allows Local Execution of Code. (CVE-2025-8875)

  - Improper Input Validation vulnerability in N-able N-central allows OS Command Injection. (CVE-2025-8876)
  
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
