CVE-2020-6577Public exploitNetwork attack vector

Database reading and modification via unescaped language code

Published Mar 19, 2021 · Updated Aug 4, 2024

SQL injection in the IT-Recht Kanzlei plugin in Zen Cart German 1.5.6c allows remote authenticated users to read or modify its database. The it_recht_kanzlei_api.php handler embeds the XML rechtstext_language value as $language_code in two unprepared, unescaped SQL queries. Exploitation requires a valid randomly generated plugin token and exposes blind query results through timing behavior.
