CVE-2023-6971Network attack vector

Unauthenticated code execution via header-controlled include

Published Dec 23, 2023 · Updated Aug 2, 2024

Remote file inclusion in Clever Widgets Backup Migration 1.0.8 through 1.3.9 allows remote attackers to execute PHP code. The backup-heart.php endpoint assigns the content-dir HTTP header to an include path and loads a PHP file from that attacker-controlled location. Exploitation requires unauthenticated network access and allow_url_include enabled in PHP, a deprecated setting that is disabled by default.
