Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Cleartext transmission of sensitive information

EUVDB-ID: #VU18967

Risk: Medium

CVSSv4.0: 1.1 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-12781

CWE-ID: CWE-319 - Cleartext Transmission of Sensitive Information

Exploit availability: No

Description

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.
