CVE-2020-8865

This vulnerability allows remote attackers to execute local PHP files on
affected installations of Horde Groupware Webmail Edition 5.2.22.
Authentication is required to exploit this vulnerability. The specific flaw
exists within edit.php. When parsing the params[template] parameter, the
process does not properly validate a user-supplied path prior to using it
in file operations. An attacker can leverage this in conjunction with other
vulnerabilities to execute code in the context of the www-data user. Was
ZDI-CAN-10469.
