"The version of the Tenable Identity Exposure running on the remote host is prior to 3.93.4. It is, therefore, affected by
multiple vulnerabilities according to advisory TNS-2025-07, including the following:

  - Inconsistent interpretation of http requests ('http request/response smuggling') in ASP.NET Core allows an authorized 
    attacker to bypass a security feature over a network. (CVE-2025-55315)

  - Improper link resolution before file access ('link following') in .NET allows an authorized attacker to elevate 
    privileges locally. (CVE-2025-55247)

  - Inadequate encryption strength in .NET, .NET Framework, Visual Studio allows an authorized attacker to disclose 
    information over a network. (CVE-2025-55248)

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