Summary: IP camera with optical character recognition (OCR) software for automatic  
number plate recognition (ANPR) also equipped with ADR system that enables it to read  
the Hazard Identification Number (HIN, also known as the Kemler Code) and UN number  
of any vehicle captured in free-flow mode. TARGA is fully accurate in reading number  
plates of vehicles travelling at high speed. Its varifocal, wide-angle lens makes  
this camera suitable for all installation conditions. Its built-in OCR software works  
as an automatic and independent system without the need of a computer, thus giving  
autonomy to the device even in the event of an interruption in the connection between  
the camera and the operations centre.  
  
Desc: The ANPR camera suffers from an unauthenticated arbitrary file disclosure vulnerability.  
Input passed through the Download Archive in Storage page using get_file.php script is  
not properly verified before being used to download files. This can be exploited to  
disclose the contents of arbitrary and sensitive files via directory traversal attacks  
and aid the attacker to disclose clear-text credentials resulting in authentication  
bypass.
