TITLE

Siemens SIMATIC WinCC Arbitrary File Read Vulnerability

DESCRIPTION

WebNavigator in Siemens WinCC 7.0 SP3 and earlier, as used in SIMATIC PCS7 and other products, stores sensitive information under the web root with insufficient access control, which allows remote attackers to read a (1) log file or (2) configuration file via a direct request. Siemens SIMATIC is an automation software in a single engineering environment. The Siemens SIMATIC WinCC WebNavigator component incorrectly handles input, allowing an attacker to read system files using a directory traversal sequence. Siemens SIMATIC WinCC is prone to information-disclosure, SQL-injection, directory-traversal, and cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied input. The attacker may exploit the information-disclosure issue and directory-traversal issues to gain access to sensitive information that may lead to further attacks. The attacker may exploit the SQL-injection issue to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. An attacker may leverage the cross-site scripting issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks. Siemens SIMATIC WinCC 7.0 SP3 and prior versions are vulnerable. WinCC flexible is a human-machine interface used in some machine or process applications. The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to perform certain unspecified actions when a logged-in administrative user visits a specially crafted web page. ---------------------------------------------------------------------- The final version of the CSI 6.0 has been released.

This can be exploited to manipulate SQL queries by injecting arbitrary SQL code. 4) An error within the ActiveX control can be exploited to disclose the username and password of an authenticated user.
