A vulnerability classified as critical has been found in Telecommunication Software SAMwin Contact Center Suite 5.1. This affects the function getCurrentDBVersion in the library SAMwinLIBVB.dll of the component Database Handler. The manipulation with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, and integrity.

The weakness was shared 03/13/2014 by Tobias Ospelt and Max Moser with modzero AG as MZ-13-06 as not defined advisory (Website). The advisory is shared at modzero.ch. The vendor cooperated in the coordination of the public release. This vulnerability is uniquely identified as CVE-2013-10003. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details and a public exploit are known. MITRE ATT&CK project uses the attack technique T1505 for this issue. The advisory points out:

Due to the absence of any middleware sanitizing and verifying input data send by the SAMwin Agent, arbitrary SQL commands can be executed from the username field of the SAMwin Agent login mask. When a SAMwin Agent user logs in, the username and password will be compared against values that are stored in the database. By terminating the username with a single quote character, any person with access to the SAMwin Agent login form can execute malicious SQL statements. For example, the following string can be used as username to verify the SQL command execution on the SQL server.

A public exploit has been developed by Tobias Ospelt/Max Moser in SQL and been published immediately after the advisory. The exploit is shared for download at modzero.ch. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 174 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 6.2 eliminates this vulnerability.
