Security readout for executives and security teams
MaxCMS 3.11.20b has a remote file inclusion flaw that can let an outside attacker make the server run attacker-supplied PHP. For a business, any internet-facing legacy MaxCMS instance should be treated as a serious compromise risk until verified isolated, removed, or remediated. Exposure is most likely limited to legacy MaxCMS 3.11.20b deployments where includes/file_manager/special.php is reachable by untrusted users. The source bundle does not provide CPEs, deployment prevalence, or affected versions beyond 3.11.20b. Prioritize as high for any exposed instance because the described impact is arbitrary PHP execution. If MaxCMS is not present, business urgency is low, but legacy asset discovery should confirm that assumption. Mitigation focus: Identify and prioritize any MaxCMS 3.11.20b systems.; Check vendor or advisory guidance for a fixed version or official workaround.; Remove or decommission exposed legacy MaxCMS where no maintained fix exists..
