CVE-2020-13568Public exploitNetwork attack vector

Authenticated SQL injection via unsanitized group identifier

Published Apr 13, 2021 · Updated Aug 4, 2024

SQL injection in phpGACL 3.3.7 allows remote authenticated users to execute arbitrary SQL through the web administration interface. The edit_group.php Submit path passes the POST group_id value unsanitized through edit_group() to get_group_data(), which concatenates it into a SELECT statement. A valid session cookie and access to group administration are required; injected SQL can read or alter database data or interrupt database operations.
