Selea Targa IP OCR-ANPR Camera Unauthenticated Directory Traversal File Disclosure Vendor: Selea s.r.l. Product web page: https://www.selea.com Affected version: Model: iZero Targa 512 Targa 504 Targa Semplice Targa 704 TKM Targa 805 Targa 710 INOX Targa 750 Targa 704 ILB Firmware: BLD201113005214 BLD201106163745 BLD200304170901 BLD200304170514 BLD200303143345 BLD191118145435 BLD191021180140 BLD191021180140 CPS: 4.013(201105) 3.100(200225) 3.005(191206) 3.005(191112) 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.
