Latest Weidmüller Industrial Ethernet switch vulnerabilities #
Multiple vulnerabilities have been disclosed in certain models and versions of Weidmüller Industrial Ethernet switch firmware. These vulnerabilities would allow a remote, unauthenticated attacker to execute arbitrary commands or perform denial-of-service against vulnerable devices.
- CVE-2025-41651 and has been rated critical with a CVSS score of 9.8.
- CVE-2025-41652 and has been rated critical with a CVSS score of 9.8.
- CVE-2025-41649 and has been rated high with a CVSS score of 7.5.
- CVE-2025-41650 and has been rated high with a CVSS score of 7.5.
- CVE-2025-41653 and has been rated high with a CVSS score of 7.5.
The following models and versions are affected
- IE-SW-VL08MT-8TX firmware versions prior to 3.5.36
- IE-SW-PL10M-3GT-7TX firmware versions prior to 3.3.34
- IE-SW-PL10MT-3GT-7TX firmware versions prior to 3.3.34

What is the impact? #
Successful exploitation of the missing authentication or authentication bypass vulnerabilities would allow an attacker to execute arbitrary commands on vulnerable switches, allowing them to take full control of affected devices. Three of the other vulnerabilities allow an attacker to potentially disrupt system operations and cause a denial-of-service against vulnerable switches.
Are any updates or workarounds available? #
Weidmüller firmware release notes indicate that the following models and versions are no longer vulnerable. Upgrade affected systems to the new firmware versions.
- IE-SW-VL05M-5TX and IE-SW-VL05MT-5TX to version 3.6.32
- IE-SW-VL08MT-8TX, IE-SW-VL08MT-5TX-1SC-2SCS, IE-SW-VL08MT-6TX-2SC, IE-SW-VL08MT-6TX-2ST and IE-SW-VL08MT-6TX-2SCS to version 3.5.36
- IE-SW-PL10M-3GT-7TX and IE-SW-PL10MT-3GT-7TX to version 3.3.34
- IE-SW-PL16M-16TX and IE-SW-PL16MT-16TX to version 3.4.32
- IE-SW-PL18M-2GC-16TX and IE-SW-PL18MT-2GC-16TX to version 3.4.40
How do I find Weidmüller Industrial Ethernet switches with runZero? #
From the Asset Inventory, use the following query to locate potentially impacted assets:
(hw:"Weidmüller IE-SW-VL08MT-8TX" OR hw:"Weidmüller IE-SW-PL10M-3GT-7TX" OR hw:"Weidmüller IE-SW-PL10MT-3GT-7TX" OR hw:"Weidmüller IE-SW-PL16M-16TX" OR hw:"Weidmüller IE-SW-PL16MT-16TX" OR hw:"Weidmüller IE-SW-PL18M-2GC-16TX" OR hw:"Weidmüller IE-SW-PL18MT-2GC-16TX" OR hw:"Weidmüller IE-SW-VL05M-5TX" OR hw:"Weidmüller IE-SW-VL05MT-5TX" OR hw:"Weidmüller IE-SW-VL08MT-5TX-1SC-2SCS" OR hw:"Weidmüller IE-SW-VL08MT-6TX-2SC" OR hw:"Weidmüller IE-SW-VL08MT-6TX-2SCS" OR hw:"Weidmüller IE-SW-VL08MT-6TX-2ST")About runZero
runZero, a network discovery and asset inventory solution, was founded in 2018 by HD Moore, the creator of Metasploit. HD envisioned a modern active discovery solution that could find and identify everything on a network–without credentials. As a security researcher and penetration tester, he often employed benign ways to get information leaks and piece them together to build device profiles. Eventually, this work led him to leverage applied research and the discovery techniques developed for security and penetration testing to create runZero.
