Vulnerability Note VU#278785
DevonIT weak authentication and buffer overflow in /usr/bin/tm-console-bin
The DevonIT management tool for thin clients uses a shared secret that is transmitted over the network in the clear. The /usr/bin/tm-console-bin application contains a buffer overflow, which may allow an attacker to execute arbitrary code.
The management tool transmits an unencrypted shared secret over the network to authenticate with clients. This traffic can then be used by an attacker to mimic a thin-manager server and control thin clients.
An attacker able to sniff traffic created by the management tool will be able to compromise the configuration of thin clients. An attacker may be able to exploit a buffer overflow in /usr/bin/tm-console-bin to execute arbitrary code.
We are currently unaware of a practical solution to this problem.
Implement appropriate firewall rules so clients will only talk to a legitimate management server.
