Overview

django-basic-auth-ip-whitelist is a Hide your Django site behind basic authentication mechanism with IP whitelisting support.

Affected versions of this package are vulnerable to Timing Attack. Potential timing attack exists on websites where the basic authentication is used or configured, i.e. BASIC_AUTH_LOGIN and BASIC_AUTH_PASSWORD is set. Currently the string comparison between configured credentials and the ones provided by users is performed through a character-by-character string comparison. This enables a possibility that attacker may time the time it takes the server to validate different usernames and password, and use this knowledge to work out the valid credentials.

Remediation
