"The version of MongoDB installed on the remote host is 6.0 prior to 6.0.21, 7.0 prior to 7.0.17 and 8.0 prior to 
8.0.5. It is, therefore, affected by a vulnerability as referenced in the SERVER-106748 advisory.

  - The MongoDB Server is susceptible to a denial of service vulnerability due to improper handling of 
    specific date values in JSON input when using OIDC authentication. This can be reproduced using the mongo 
    shell to send a malicious JSON payload leading to an invariant failure and server crash. This issue 
    affects MongoDB Server v7.0 versions prior to 7.0.17 and MongoDB Server v8.0 versions prior to 8.0.5. The 
    same issue affects MongoDB Server v6.0 versions prior to 6.0.21, but an attacker can only induce denial 
    of service after authenticating. (CVE-2025-6709)

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