Allocation of resources without limits or throttling in ASP.NET Core allows an unauthorized attacker to deny service over a network.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Allocation of resources without limits or throttling in ASP.NET Core allows an unauthorized attacker to
    deny service over a network. (CVE-2025-26682)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Allocation of resources without limits or throttling in ASP.NET Core allows an unauthorized attacker to     deny service over a network. (CVE-2025-26682)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by a vulnerability as referenced in the USN-7427-1 advisory.

    James Newton-King discovered that .NET did not properly limit resource allocation when handling certain     HTTP/3 requests. An attacker could possibly use this issue to cause 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 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 vendor advisory.

  - Allocation of resources without limits or throttling in ASP.NET Core allows an unauthorized attacker to     deny service over a network. (CVE-2025-26682)

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