~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Overview:

Password Safe and Repository Enterprise is a password management
software for companies with many features.

The manufacturer MATESO GmbH describes the product as follows (see [1]):

"Manage your passwords in the company according to your security needs!
Features such as password policies, multi-eyes principle, workflow and
task system makes management productive and safe.

The integrated rights management system with data transfer option and
automatic synchronization with Active Directory ensures that your
employees can only access data which they are entitled to."

Due to a SQL injection vulnerability in the user authentication of the
offline mode, an attacker can gain unauthorized access to the
synchronized Password Safe database.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Vulnerability Details:

The SySS GmbH found a SQL injection vulnerability in the user
authentication functionality of the offline mode which can be
exploited by an unauthenticated user with access to the offline
database.

By exploiting this SQL injection vulnerability, an attacker can gain
unauthorized access to a synchronized Password Safe database (offline
database), for example by bypassing the user authentication with a
suitable SQL attack vector (see PoC section).

In the context of the user authentication functionality in the offline
mode, the following SQL statement is used which is vulnerable to
SQL injection via the parameter user name in the WHERE clause due to
insufficient user input validation:

SELECT ID FROM tdUsers WHERE UPPER(Name) = UPPER('<USERNAME>') and LoginPassword = '<MD5 PASSWORD HASH>' and Inactive = 0 and Deleted = 0

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Proof of Concept (PoC):

In order to gain unauthorized access to an offline database, the
following SQL attack vector

') or 1=1 --

can be used as user name in combination with an arbitrary password.

If a user name containing an apostrophe (') is used, the password
management software Password Safe and Repository Enterprise throws an
exception and shows a detailed error message with the failed SQL
statement.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Solution:

According to information by the MATESO GmbH, the described security
issues have been fixed in the software version 7.5.0.2255 that was
released on October 5, 2015.

Please contact the manufacturer for further information or support.
