-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Advisory ID: SYSS-2015-034 Product(s): Password Safe and Repository Enterprise Manufacturer: MATESO GmbH Affected Version(s): 7.4.4 Build 2247 Tested Version(s): 7.4.4 Build 2247 Vulnerability Type: SQL Injection (CWE-89) Authentication Bypass Using an Alternate Path or Channel (CWE-288) Risk Level: High Solution Status: Fixed Manufacturer Notification: 2015-07-09 Solution Date: 2015-10-05 Public Disclosure: 2015-10-12 CVE Reference: Not yet assigned Author of Advisory: Matthias Deeg (SySS GmbH) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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.
