"The version of DELMIA Apriso installed on the remote host is Release 2020 through 2025. It is, therefore, 
affected by a deserialization of untrusted data vulnerability (CVE-2025-5086) that could allow an unauthenticated 
attacker to execute arbitrary code remotely. Exploitation involves sending a specially crafted POST request, 
often Base64-encoded and GZIP-compressed, which may lead to full system compromise, disruption of MES/MOM 
operations, data exfiltration, and lateral movement.

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