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.”

Cybersecurity

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 –

  • CVE-2024-52558 (CVSS score: 5.3) – An integer underflow flaw that can allow an unauthenticated attacker to send a malformed HTTP request, resulting in a crash
  • CVE-2024-52320 (CVSS score: 9.8) – An operating system command injection flaw that can allow an unauthenticated attacker to send commands through a malicious HTTP request, resulting in remote code execution
  • CVE-2024-48871 (CVSS score: 9.8) – A stack-based buffer overflow flaw that can allow an unauthenticated attacker to send a malicious HTTP request, resulting in remote code execution

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.

What is Firewall? A Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. At its most basic, a firewall is essentially the barrier that sits between a private internal network and the public Internet.

 

Secure your network at the gateway against threats such as intrusions, Viruses, Spyware, Worms, Trojans, Adware, Keyloggers, Malicious Mobile Code (MMC), and other dangerous applications for total protection in a convenient, affordable subscription-based service. Modern threats like web-based malware attacks, targeted attacks, application-layer attacks, and more have had a significantly negative effect on the threat landscape. In fact, more than 80% of all new malware and intrusion attempts are exploiting weaknesses in applications, as opposed to weaknesses in networking components and services. Stateful firewalls with simple packet filtering capabilities were efficient blocking unwanted applications as most applications met the port-protocol expectations. Administrators could promptly prevent an unsafe application from being accessed by users by blocking the associated ports and protocols.
