Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Cleartext transmission of sensitive information (CVE-ID: CVE-2019-12781)

The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to django.http.HttpRequest.scheme, when deployed behind a reverse-proxy, does not correctly treat requests sent over HTTP protocol, assuming that a secure protocol is used for communication. A remote attacker with ability to force victim to use HTTP instead of HTTPS protocol can perform man-in-the-middle (MitM) attack and intercept communication in cleat text.


2) Resource management error (CVE-ID: CVE-2019-14232)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to usage of truncatechars_html and truncatewords_html template filters in django.utils.text.Truncator during evaluation of HTML content. A remote attacker can pass large content in HTML format to the application and trigger resource exhaustion.


3) Resource management error (CVE-ID: CVE-2019-14233)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to usage of django.utils.html.strip_tags() during evaluation of HTML content. A remote attacker can pass large content in HTML format to the application and trigger resource exhaustion.


4) SQL injection (CVE-ID: CVE-2019-14234)

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data in django.contrib.postgres.fields.JSONField and django.contrib.postgres.fields.HStoreField. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.


5) Resource management error (CVE-ID: CVE-2019-14235)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an error when parsing URF-8 data with django.utils.encoding.uri_to_iri(). A remote attacker can pass specially crafted content to the application and consume all available memory on the system.
