A heap-based buffer overflow vulnerability exists in XML parser functionality in the HiDraw. An authenticated malicious user with local access can exploit this vulnerability using a specially crafted XML file which may lead to memory corruption and potential arbitrary code execution. Successful exploitation could result in application crashes (denial of service) and compromise the confidentiality and integrity of the affected system.

  • MitigationMACH HiDrawcisa_csaf_ot

    Hitachi's General Mitigation Factors/Workarounds: Recommended security practices and firewall configurations can help protect a process control network from attacks that originate from outside the network. Such practices include that process control systems are physically protected from direct access by unauthorized personnel, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed, and others that have to be evaluated case by case. Process control systems should not be used for Internet surfing, instant messaging, or receiving e-mails. Portable computers and removable storage media should be carefully scanned for viruses before they are connected to a control system. Proper password policies and processes should be followed.
