DESCRIPTION:
Some vulnerabilities have been reported in phpRechnung, which can be
exploited by malicious people to bypass certain security
restrictions.

The vulnerabilities are caused due to e.g. the "CheckUser()",
"CheckAdmin()", and "CheckAdminGroup2()" functions in
include/phprechnung.inc.php not properly restricting access to users
or administrators, which can be exploited to e.g. access certain
functionality without being properly authenticated.

The vulnerabilities are reported in versions prior to 1.6.1.

SOLUTION:
Update to version 1.6.1.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
