  script_set_attribute(attribute:"description", value:
"The version of aioHTTP installed on the remote host is prior to 3.9.4. It is, therefore, affected by a
cross-site scripting (XSS) vulnerability. aiohttp is an asynchronous HTTP client/server framework for asyncio 
and Python. A XSS vulnerability exists on index pages for static file handling. This vulnerability is fixed 
in 3.9.4. We have always recommended using a reverse proxy server (e.g. nginx) for serving static files. 
Users following the recommendation are unaffected. Other users can disable `show_index` if unable to upgrade.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported 
version number. Also note that this plugin does not distinguish between Python packages installed via the OS 
package manager, Python packages installed via PIP, or other sources. As a result, packages provided by your 
OS package repository may have backported fixes that this plugin may incorrectly report as vulnerable. Please 
refer to the OS-specific plugins for CVE-2024-27306 to check for backported fixes.");
