Versions of the package djoser before 2.3.0 are vulnerable to Authentication Bypass when the authenticate() function fails. This is because the system falls back to querying the database directly, granting access to users with valid credentials, and eventually bypassing custom authentication checks such as two-factor authentication, LDAP validations, or requirements from configured AUTHENTICATION_BACKENDS.

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has a package installed that is affected by a vulnerability as referenced in the USN-7354-1 advisory.

    Diego Cebrin discovered that djoser did not properly handle user authentication. An attacker with valid     credentials could possibly use this to bypass authentication checks, such as two-factor authentication, to     gain unintended access.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

    Package        : djoser     Version        : 2.1.0-1+deb11u1     CVE ID         : CVE-2024-21543     Debian Bug     : 1089915

    djoser is a REST implementation of Django authentication system.
    It has a very low install count according to popularity contest     so you most likely don't have it installed and are thus not affected.

    For Debian 11 bullseye, this problem has been fixed in version     2.1.0-1+deb11u1.
    (Similar update for debian 12 bookworm is currently being processed.)

    We recommend that you upgrade your djoser packages.

    For the detailed security status of djoser please refer to     its security tracker page at:
