The Weidmueller Remote I/O (IP20) fieldbus couplers (u-remote) are affected by several vulnerabilities of the third-party TCP/IP Niche stack. An attacker may use crafted IP packets to cause a denial of service or breach of integrity of the affected products. Weidmueller recommends restricting network access from the internet and also locally to reduce the attack vector to a manageable minimum.

Mitigatiesamenvatting

Fieldbuses (including Industrial Ethernet protocols) in general are not intended for direct connection with the internet, as they lack a proper set of security capabilities. This also applies to Weidmüller IP20 Remote I/O fieldbus couplers, which are developed and designed for operation in closed industrial networks. - Do not directly connect the affected products to the internet. - Restrict network access to the affected products by proper secured network infrastructure (e.g. routers, firewalls, DMZ, VPNs). - Restrict physical access to the industrial network and affected products (e.g cabinets, seals, closures).

Risk evaluation

A vulnerability has been discovered in the fdtCONTAINER component and application by M&M Software GmbH. As this software is part of the Weidmüller FDT/DTM Software with WI Manager, this Weidmueller software is affected by the above vulnerability as well. The fdtCONTAINER component exchanges binary data blobs with the WI Manager. The WI Manager saves these binary data blobs into a project file. If an attacker gets write access to the project file, the project file can be manipulated to contain malicious code.

Mitigatiesamenvatting

- Exchange project data only via secure exchange services - Use appropriate means to protect the project storage from unauthorized manipulation - Do not open project data from an unknown source - Reduce the user rights of the WI Manager to the necessary minimum
