CVE 描述
Tropos Wireless Mesh Routers Insufficient Entropy
Mesh OS before 7.9.1.1 on Tropos wireless mesh routers does not use a sufficient source of entropy for SSH keys, which makes it easier for man-in-the-middle attackers to spoof a device or modify a client-server data stream by leveraging knowledge of a key from a product installation elsewhere.CVE 解决方案
Tropos Networks has released customer notification and an update (Tropos
Mesh OS 7.9.1.1) for its network device embedded software. This update
can be downloaded from the Tropos software download page. Download of
the update requires a valid user name and password. The updated firmware
fixes the vulnerability by using sufficient entropy to generate unique
SSH host keys.
