Timing attack on django-basic-auth-ip-whitelist
CVE-2020-4071 · GHSA-m38j-pmg3-v5x5
- Affected
- PyPI django-basic-auth-ip-whitelist < 0.3.4
- Fixed in
- 0.3.4· Vendor fix available
- Issue
- Impact Potential timing attack exists on websites where the basic authentication is used or configured, i.e. BASICAUTHLOGIN and BASICAUTHPASSWORD 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. This attack is understood not to be realistic over the Internet. However, it may be achieved from within local networks where the website is hosted, e.g. from inside a data centre where a website's server is located. Sites protected by IP address whitelisting only are unaffected by this vulnerability. Patches This vulnerability has been fixed on version 0.3.4 of django-basic-auth-ip-whitelist. Update to version 0.3.4 as soon as possible and change basic authentication username and password…
Recommended action: Upgrade to 0.3.4 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
