The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4043-1 advisory.
It was discovered that Django incorrectly handled certain inputs. An attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 18.04 LTS, Ubuntu 18.10 and Ubuntu 19.04.
(CVE-2019-12308)
Gavin Wahl discovered that Django incorrectly handled HTTP detection when used behind a reverse-proxy.
Client requests made via HTTP would cause incorrect API results and would not be redirected to HTTPS, contrary to expectations. (CVE-2019-12781)
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
