SysLINK SL-1000 Machine-to-Machine (M2M) Modular Gateway devices with firmware before 01A.8 use the same hardcoded encryption key across different customers' installations, which allows attackers to defeat cryptographic protection mechanisms by leveraging knowledge of this key from another installation.

flu.cgi in the web interface on SysLINK SL-1000 Machine-to-Machine (M2M) Modular Gateway devices with firmware before 01A.8 allows remote authenticated users to execute arbitrary commands via the 5066 (aka dnsmasq) parameter.

The web interface on SysLINK SL-1000 Machine-to-Machine (M2M) Modular Gateway devices with firmware before 01A.8 has a default password, which makes it easier for remote attackers to obtain access via unspecified vectors.
