CVE-2020-6008Public exploitNetwork attack vector

Remote code execution via unchecked export filename

Published Mar 31, 2020 · Updated Aug 4, 2024

Arbitrary file write in LifterLMS before 3.37.15 allows remote authenticated users to execute PHP code through a crafted export. export_admin_table passes an attacker-chosen filename to generate_export_file, which checks the default CSV type but not the filename extension before appending exported data under LLMS_TMP_DIR. A registered student can place PHP in a profile name, obtain the AJAX nonce, request a .php export, and browse the generated file to run code on the server.
