Description
Hirschmann HiOS devices versions prior to 08.1.00 and 07.1.01 contain a denial of service vulnerability in the EtherNet/IP stack where improper handling of packet length fields allows remote attackers to crash or hang the device. Attackers can send specially crafted UDP EtherNet/IP packets with a length value larger than the actual packet size to render the device inoperable.

Description Hirschmann Industrial HiVision versions 08.1.03 prior to 08.1.04 and 08.2.00 contains an untrusted search path vulnerability that allows local attackers to execute arbitrary binaries by placing a malicious binary in the path of a configured external application. Attackers can exploit insufficient path sanitization to cause the execution of a malicious binary instead of the intended application, potentially resulting in execution with elevated privileges.
