An issue was discovered in Django 1.11 before 1.11.22, 2.1 before 2.1.10, and 2.2 before 2.2.3. An HTTP request is not redirected to HTTPS when the SECURE_PROXY_SSL_HEADER and SECURE_SSL_REDIRECT settings are used, and the proxy connects to Django via HTTPS. In other words, django.http.HttpRequest.scheme has incorrect behavior when a client uses HTTP.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1324 advisory.

  - Django: Incorrect HTTP detection with reverse-proxy connecting via HTTPS (CVE-2019-12781)

  - Django: backtracking in a regular expression in django.utils.text.Truncator leads to DoS (CVE-2019-14232)

  - Django: the behavior of the underlying HTMLParser leading to DoS (CVE-2019-14233)

  - Django: SQL injection possibility in key and index lookups for JSONField/HStoreField (CVE-2019-14234)

  - Django: Potential memory exhaustion in django.utils.encoding.uri_to_iri() (CVE-2019-14235)

update to 2.1.10, security fix for CVE-2019-12781

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Three security issues were found in Django, a Python web development framework, which could result in denial of service, incomplete sanitisation of clickable links or missing redirects of HTTP requests to HTTPS.

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 certain requests. An attacker could possibly use this issue to bypass credentials and access administrator interface. (CVE-2019-12781).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Django security releases issued :

When deployed behind a reverse-proxy connecting to Django via HTTPS, django.http.HttpRequest.scheme would incorrectly detect client requests made via HTTP as using HTTPS. This entails incorrect results for is_secure(), and build_absolute_uri(), and that HTTP requests would not be redirected to HTTPS in accordance with SECURE_SSL_REDIRECT.
