CVE-2023-40619Network attack vector

Remote code execution via unsafe POST deserialization

Published Sep 20, 2023 · Updated Sep 25, 2024

Deserialization of untrusted data in phpPgAdmin 7.14.4 and earlier allows remote attackers to execute code via crafted table-management requests. The tables.php table-management path passes the ma[] POST parameter directly to PHP unserialize(), and other paths repeat the unsafe operation. No authentication or user interaction is required; successful object injection executes code in the web application's server context.
