TITLE

plural Siemens Product HmiLoad Vulnerable to directory traversal

DESCRIPTION

Directory traversal vulnerability in HmiLoad in the runtime loader in Siemens WinCC flexible 2004, 2005, 2007, and 2008; WinCC V11 (aka TIA portal); the TP, OP, MP, Comfort Panels, and Mobile Panels SIMATIC HMI panels; WinCC V11 Runtime Advanced; and WinCC flexible Runtime, when Transfer Mode is enabled, allows remote attackers to execute, read, create, modify, or delete arbitrary files via a .. (dot dot) in a string. plural Siemens Product runtime loader HmiLoad Is Transfer A directory traversal vulnerability exists when the mode is enabled.By a third party .. ( Dot dot ) Arbitrary files may be executed, read, created, modified, or deleted via strings containing. Miniweb has a security vulnerability that allows an attacker to submit a specially crafted HTTP POST request to allow the server to access any illegal memory area while checking the extension of the requested file. Siemens SIMATIC WinCC is a multi-user system that provides complete monitoring and data acquisition (SCADA) functionality for the industrial sector, from single-user systems to redundant server and remote web client solutions. HmiLoad provides functions that read data and unicode strings with stack-based buffer overflows, allowing an attacker to exploit a vulnerability to execute arbitrary code. HmiLoad has multiple security vulnerabilities that allow an attacker to stop a service or crash a service in multiple ways. A directory traversal vulnerability exists in the HmiLoad server that allows reading, writing, and deleting arbitrary files outside of the specified directory. Siemens SIMATIC is an automation software in a single engineering environment. A security vulnerability exists in the Siemens SIMATIC WinCC HMI web server. When the transfer mode is enabled, the runtime loader listens on the 2308/TCP or 50523/TCP port, but does not verify the submitted string, allowing the attacker to read and write any file in the file system. Attackers can exploit these issues to execute arbitrary code in the context of the affected application, read/write or delete arbitrary files outside of the server root directory, or cause denial-of-service conditions; other attacks may also be possible.

The vulnerabilities are confirmed in version 2008 SP2 Upd13 (K01.03.02.13_01.02.00.01). Other versions may also be affected. SOLUTION: Restrict access to trusted hosts only.
