-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Advisory ID: SYSS-2015-036 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: Credentials Management (CWE-255) Violation of Secure Design Principles (CWE-657) Risk Level: High Solution Status: Fixed Manufacturer Notification: 2015-07-09 Solution Date: 2016-10-18 Public Disclosure: 2017-04-10 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 vendor 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." ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: SySS GmbH found out that synchronized databases (offline databases) created by a specific user also contain sensitive data of other users, for example login credentials. The password information of other users are stored as raw, unsalted MD5 hash values in the database table tdUsers (see SYSS-2015-037). Thus, by having access to an offline database, it is possible to access password information of other users, for example the MD5 password hash of the built-in administrator account. This password information may be recovered during password guessing attacks and used for accessing foreign user data in an unauthorized way or for performing privilege escalation attacks in the online mode. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): In the offline mode of the password management software Password Safe and Repository, it is possible to manipulate SQL statements due to the violation of secure design principles and SQL injection vulnerabilities (see SYSS-2015-035). By using the following SQL statement, user information of all users unnecessarily stored in the database table tdUsers can be retrieved from an offline database and extracted from memory of the password management software, for example by using a modified client software: SELECT * FROM tdUsers ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution: The MATESO GmbH released the new software version Password Safe and Repository Enterprise 8 that is not affected by the described security issues. Please contact the manufacturer for further information or support. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Disclosure Timeline: 2015-07-09: Vulnerability reported to manufacturer 2015-07-09: Manufacturer acknowledges e-mail with SySS security advisory 2015-07-30: Scheduling of the publication date in agreement with the manufacturer 2015-10-02: Rescheduling of the publication date in agreement with the manufacturer 2016-10-18: Manufacturer presents new software version with fixed security issues 2017-04-10: Public release of security advisory ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ References: [1] Product website for Password Safe and Repository Enterprise http://www.passwordsafe.de/en/products/business/enterprise-edition.html [2] SySS Security Advisory SYSS-2015-036 https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2015-036.txt [3] SySS Responsible Disclosure Policy https://www.syss.de/en/news/responsible-disclosure-policy/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Credits: This security vulnerability was found by Matthias Deeg of SySS GmbH.
