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+.
Add your gear to cvedb and we'll alert you only when concretecms ships something exploited.
