Security readout for executives and security teams

CVE-2018-10547 is a reflected cross-site scripting flaw in PHP’s PHAR error pages. A vulnerable server can echo attacker-controlled request data when a .phar request returns 403 or 404. Impact is browser-side and depends on whether users view a crafted response in a sensitive site context. Exposure is most likely on legacy PHP 5.6, 7.0, 7.1, or 7.2 deployments that serve or route requests for .phar files and expose PHP-generated PHAR error pages to users. Treat this as a legacy platform hygiene issue unless a vulnerable public PHP service is confirmed. Prioritize internet-facing systems and systems where browser sessions carry sensitive privileges. Mitigation focus: Upgrade PHP beyond the fixed versions named by PHP and distribution advisories.; Apply relevant vendor or distribution security updates for supported platforms.; Review vendor guidance for appliances or bundled PHP runtimes..
