#VU31195 Insufficiently protected credentials in Django - CVE-2018-16984

Vulnerability identifier: #VU31195

Vulnerability risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2018-16984

CWE-ID: CWE-522

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
Django
Web applications / CMS

Vendor: Django Software Foundation

Description

The vulnerability allows a remote privileged user to gain access to sensitive information.

An issue was discovered in Django 2.1 before 2.1.2, in which unprivileged users can read the password hashes of arbitrary accounts. The read-only password widget used by the Django Admin to display an obfuscated password hash was bypassed if a user has only the "view" permission (new in Django 2.1), resulting in display of the entire password hash to those users. This may result in a vulnerability for sites with legacy user accounts using insecure hashes.

Mitigation
Install update from vendor's website.

Vulnerable software versions

Django: 2.1 - 2.1.1
