This security bulletin contains information about 3 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2019-6975)

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

The vulnerability exists due to improper memory operations that exist when the django.utils.numberformat.format() function receives a decimal with a large number of digits or a large component. A remote attacker can send a request that submits malicious input, consume excessive amounts of memory resources, resulting in a DoS condition.


2) Cross-site scripting (CVE-ID: CVE-2019-12308)

The vulnerability exists due to insufficient sanitization of URL within the AdminURLFieldWidget. A remote attacker can trick the victim to follow a specially crafted link and display a clickable JavaScript link.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


3) 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.
