CVE-2023-42802Public exploitNetwork attack vector

Unauthenticated code execution via unverified object instantiation

Published Nov 2, 2023 · Updated Sep 5, 2024

Improper input validation in GLPI 10.0.7 through 10.0.9 allows remote attackers to upload executable PHP files without authentication. The object-instantiation path fails to verify the requested object before writing an attacker-supplied PHP file into web-accessible directories. Code execution requires web-server access to the destination plus a compatible server configuration and system library; otherwise the flaw still permits file upload.
