CVE-2020-15226

In GLPI before version 9.5.2, there is a SQL Injection in the API’s search
function. Not only is it possible to break the SQL syntax, but it is also
possible to utilise a UNION SELECT query to reflect sensitive information
such as the current database version, or database user. The most likely
scenario for this vulnerability is with someone who has an API account to
the system. The issue is patched in version 9.5.2. A proof-of-concept with
technical details is available in the linked advisory.
