The remote Fedora 38 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2023-bc1f081ca0 advisory.

  • aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel). These bugs have been addressed in commit d5c12ba89 which has been included in release version 3.8.6. Users are advised to upgrade. There are no known workarounds for these issues. (CVE-2023-47627)

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