Username enumeration through timing difference in mod_wsgi authentication handler

5.3 / 10

MEDIUM

CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N

Description

An issue was discovered in 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28.
The `django.contrib.auth.handlers.modwsgi.check_password()` function for authentication via `mod_wsgi` allows remote attackers to enumerate users via a timing attack.
Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.
Django would like to thank Stackered for reporting this issue.
