SUSE SLED15 / SLES15 Security Update : python-Flask-Security-Too (SUSE-SU-2022:3093-1)

high Nessus Plugin ID 164919

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2022:3093-1 advisory.

 - The Python Flask-Security-Too package is used for adding security features to your Flask application. It is an is a independently maintained version of Flask-Security based on the 3.0.0 version of Flask- Security. In Flask-Security-Too from version 3.3.0 and before version 3.4.5, the /login and /change endpoints can return the authenticated user's authentication token in response to a GET request. Since GET requests aren't protected with a CSRF token, this could lead to a malicious 3rd party site acquiring the authentication token. Version 3.4.5 and version 4.0.0 are patched. As a workaround, if you aren't using authentication tokens - you can set the SECURITY_TOKEN_MAX_AGE to 0 (seconds) which should make the token unusable. (CVE-2021-21241)

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

Solution

Update the affected python3-Flask-Security-Too package.
