The version of the Tornado Python library installed on the remote host is prior to 6.5.5. It is, therefore, affected by multiple vulnerabilities:

  - Tornado is a Python web framework and asynchronous networking library. In versions of Tornado prior to     6.5.5, the only limit on the number of parts in multipart/form-data is the max_body_size setting     (default 100MB). Since parsing occurs synchronously on the main thread, this creates the possibility of     denial-of-service due to the cost of parsing very large multipart bodies with many parts. This     vulnerability is fixed in 6.5.5. (CVE-2026-31958)

  - In Tornado before 6.5.5, cookie attribute injection could occur because the domain, path, and samesite     arguments to .RequestHandler.set_cookie were not checked for crafted characters. (CVE-2026-35536)

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

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8198-1 advisory.

    It was discovered that Tornado incorrectly handled parsing of large multipart request bodies. An attacker     could possibly use this issue to cause a denial of service. (CVE-2026-31958)

    It was discovered that Tornado did not properly validate characters in cookie values. An attacker could     possibly use this issue to inject arbitrary cookie attributes. (CVE-2026-35536)
