OleumTech Wireless Sensor Network devices allow remote attackers to obtain sensitive information about sensor nodes or spoof devices by reading cleartext protocol data.

OleumTech WIO DH2 Wireless Gateway and Sensor Wireless I/O Modules allow remote attackers to execute arbitrary code via packets that report a high battery voltage.

OleumTech WIO DH2 Wireless Gateway and Sensor Wireless I/O Modules, when BreeZ is used, do not require authentication for reading the site security key, which allows physically proximate attackers to spoof communication by obtaining this key after use of direct hardware access or manual-setup mode.

OleumTech WIO DH2 Wireless Gateway and Sensor Wireless I/O Modules rely exclusively on a time value for entropy in key generation, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by predicting the time of project creation.
