CVE-2019-19844
Description
A flaw was found in Django where it did not sanitize the email input from the password recovery form. An attacker with the knowledge of the victim user’s email address could use this flaw to reset the victim user’s password and retrieve the reset link to gain access and take over their account.
Statement
This flaw depends upon the use of Django's password reset functionality. The following products ship the flawed code but do not use this functionality:
- Red Hat Ceph Storage 2 and Red Hat Ceph Storage 3
- Red Hat Gluster Storage 3
- Red Hat Certified Cloud and Service Provider Certification 1
- Red Hat OpenStack Platform, all versions. No updates will be provided at this time for the RHOSP django package.
- Red Hat Satellite 6, all versions
- Red Hat Update Infrastructure 3
Mitigation
Unless the password-reset form is disabled, this flaw can only be resolved by applying updates.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
