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

The version of .NET Core SDK installed on the remote host is 6.x prior to 6.0.27, 7.x prior to 7.0.16 or 8.x prior to 8.0.2. It is, therefore, affected by multiple vulnerabilities as referenced in the February 2024 advisory:

  - A vulnerability exists in .NET where specially crafted requests may cause a resource leak, leading to a     denial of service. (CVE-2024-21392)

  - A Vulnerability exist in MsQuic.dll which might result in a peer to allocate small chunks of memory as     long as connection stays alive. (CVE-2024-26190) 

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

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 2024_Mar_12 advisory.

  - .NET and Visual Studio Denial of Service Vulnerability (CVE-2024-21392)

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

The remote Ubuntu 22.04 LTS / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6693-1 advisory.

    It was discovered that .NET did not properly handle certain specially crafted requests. An attacker could     potentially use this issue to cause a resource leak, leading to a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The Microsoft Visual Studio Products are missing security updates. It is, therefore, affected by multiple denial of service vulnerabilities. An attacker can exploit these issues to cause the affected component to deny system or application services.

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