The version of python3 installed on the remote host is prior to 3.9.19. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2024-080-01 advisory.
libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are required in the case of a large token for which multiple buffer fills are needed. (CVE-2023-52425)
An issue was found in the CPython tempfile.TemporaryDirectory
class affecting versions 3.12.2, 3.11.8, 3.10.13, 3.9.18, and 3.8.18 and prior. The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related errors. This means users which can run privileged programs are potentially able to modify permissions of files referenced by symlinks in some circumstances.
(CVE-2023-6597)
An issue was found in the CPython zipfile
module affecting versions 3.12.2, 3.11.8, 3.10.13, 3.9.18, and 3.8.18 and prior. The zipfile module is vulnerable to quoted-overlap zip-bombs which exploit the zip format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject zip archives which overlap entries in the archive. (CVE-2024-0450)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
