Introduction
===============
From vendor's website:
"Siemens FactoryLink monitors, supervises, and controls industrial
processes by enabling customers to perfect their processes and
products. Built on an advanced open architecture, FactoryLink delivers
the highest performance and flexibility to customers building vertical
applications in a wide range of industries.
Highly scaleable, FactoryLink can be used to build virtually any size
application, from the simplest Human-Machine Interface (HMI) systems to
the most complex and demanding Supervisory Control and Data Acquisition
(SCADA) systems."
Remote Stack Overflow:
======
Bug
======
CSService is a Windows service listening on port 7580.
The logging function is vulnerable to a buffer-overflow caused by the
usage of vsprintf with a stack buffer of 1024 bytes.
The vulnerability can be exploited from remote in various ways like the
passing of a big path or filter string in the file related operations
(opcodes 6, 8 and 10).

Arbitrary Files Reading and Listing:
======
Bug
======
CSService is a Windows service listening on port 7580.
All the file operations used by the service (opcodes 6, 8 and 10) allow
to specify arbitrary files and directories (absolute paths) and it's
possible for an attacker to download any remote file on the server.
Obviously it's possible also to specify directory traversal paths.

Remote Memory Corruption:
======
Bug
======
vrn.exe is a server listening on port 7579 when a project is started.
There is a particular function used to parse the text fields located in
the strings of the opcode 10.
It copies the string delimited by a ';' or a space in the stack buffer
provided by the callee function causing a stack overflow that allows a
certain control on the code flow (for example the changing of the lower
8bit of the return address or another exception).

vrn.exe is a server listening on port 7579 when a project is started.
There is a particular function used to parse the text fields located in
the strings of the opcode 9.
It copies the string delimited by a ';' or a space in the stack buffer
provided by the callee function causing a classical stack overflow.

Arbitrary File Download:

Bug
======
vrn.exe is a server listening on port 7579 when a project is started.
The opcode 8 can be used to download any arbitrary file on the system
by specifiying the full path (UNC too) or directory traversal.

CSService, connsrv and datasrv are various Windows services.
All these services are vulneable to some Denial of Service
vulnerabilities that allow to crash them due to NULL pointer
dereferences, stack exaustions and raised exceptions.
