CVE-2021-43777 is a medium-severity vulnerability affecting redash redash. It was published on November 24, 2021 and has a CVSS 3.1 base score of 6.8 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.8, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
Redash is a package for data visualization and sharing. In Redash version 10.0 and prior, the implementation of Google Login (via OAuth) incorrectly uses the `state` parameter to pass the next URL to redirect the user to after login. The `state` parameter should be used for a Cross-Site Request Forgery (CSRF) token, not a static and easily predicted value. This vulnerability does not affect users who do not use Google Login for their instance of Redash. A patch in the `master` and `release/10.x.x` branches addresses this by replacing `Flask-Oauthlib` with `Authlib` which automatically provides and validates a CSRF token for the state variable. The new implementation stores the next URL on the user session object. As a workaround, one may disable Google Login to mitigate the vulnerability.
Remediation
Check the references section for vendor advisories and patches from redash. Update redash to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
