Weidmueller security routers IE-SR-2TX are affected by multiple vulnerabilities (CVE-2025-41661, CVE-2025-41663, CVE-2025-41683, CVE-2025-41684, CVE-2025-41687). Weidmueller has released new firmware versions of the affected products to fix the vulnerabilities. Update Version 1.1.0: Added CVEs CVE-2025-41683, CVE-2025-41684 and CVE-2025-41687. Updated CVSS Score for CVE-2025-41663. Removed CVE-2025-41662.
As a general security measure, Weidmueller strongly recommends to change the default passwords and to minimize the network exposure of products. Limit access to trusted networks by using the appropriate mechanisms.
Weidmueller security routers are vulnerable to multiple vulnerabilities, that may lead to execution of arbitrary commands on affected devices with root privileges. Further information can be found under vulnerability details.

Update to version V1.62
For u-link Management API an unauthenticated remote attacker in a man-in-the-middle position can inject arbitrary commands in responses returned by WWH servers, which are then executed with elevated privileges. To get into such a position, clients would need to use insecure proxy configurations.
