TITLE
Siemens TeleControl Server Basic CreateTrace SQL Injection Remote Code Execution Vulnerability
Trust: 0.7
DESCRIPTION
A vulnerability has been identified in TeleControl Server Basic (All versions < V3.1.2.2). The affected application is vulnerable to SQL injection through the internally used 'CreateTrace' method. This could allow an unauthenticated remote attacker to bypass authorization controls, to read from and write to the application's database and execute code with "NT AUTHORITY\NetworkService" permissions. A successful attack requires the attacker to be able to access port 8000 on a system where a vulnerable version of the affected application is executed on. (ZDI-CAN-25911). This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens TeleControl Server Basic. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the CreateTrace method. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to execute code in the context of NETWORK SERVICE. Siemens TeleControl Server Basic versions prior to v3.1.2.2 have multiple SQL injection vulnerabilities that can be exploited by attackers to read and write the application's database, causing a denial of service and executing code in the operating system shell with limited "NT AUTHORITYNetworkService" permissions
