The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-c729dabeb1 advisory.
In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9 (CVE-2015-20107)
Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is disputed by a third party because the http.server.html documentation page states Warning: http.server is not recommended for production. It only implements basic security checks. (CVE-2021-28861)
An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting methods by supplying a URL that starts with blank characters. (CVE-2023-24329)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
