Cybersecurity researchers have disclosed three security flaws in Planet Technology’s WGS-804HPT industrial switches that could be chained to achieve pre-authentication remote code execution on susceptible devices.
“These switches are widely used in building and home automation systems for a variety of networking applications,” Claroty’s Tomer Goldschmidt said in a Thursday report. “An attacker who is able to remotely control one of these devices can use them to further exploit devices in an internal network and do lateral movement.”
The operational technology security firm, which carried out an extensive analysis of the firmware used in these switches using the QEMU framework, said the vulnerabilities are rooted in the dispatcher.cgi interface used to provide a web service. The list of flaws is below –
Successful exploitation of the flaws could permit an attacker to hijack the execution flow by embedding a shellcode in the HTTP request and gain the ability to execute operating system commands.
Following responsible disclosure, the Taiwanese company has rolled out patches for the shortcomings with version 1.305b241111 released on November 15, 2024.
