Concrete CMS vulnerable to Improper Authentication

Check your stack

The advisory, in context

Concrete CMS (formerly concrete5) below 8.5.10 and between 9.0.0 and 9.1.2 did not use strict comparison for the legacy_salt so that limited authentication bypass could occur if using this functionality. Remediate by updating to Concrete CMS 9.1.3+ or 8.5.10+.

Affected packages

Start with the recorded fix for your release branch. Check your installed version and test compatibility before upgrading. Fixing this advisory does not rule out other vulnerabilities in the release.
