A vulnerability has been identified in Capital Embedded AR Classic 431-422 (All versions), Capital Embedded AR Classic R20-11 (All versions < V2303), PLUSCONTROL 1st Gen (All versions), SIMOTICS CONNECT 400 (All versions < V0.5.0.0), SIMOTICS CONNECT 400 (All versions < V1.0.0.0). The total length of an ICMP payload (set in the IP header) is unchecked. This may lead to various side effects, including Information Leak and Denial-of-Service conditions, depending on the network buffer organization in memory. (FSMD-2021-0007)

MitigationPLUSCONTROL 1st Gensiemens_psirt
PLUSCONTROL devices are typically located in a separate LAN segment of energy transmission solutions, where an attacker could use these vulnerabilities to disrupt SER messages or Trace functionalities. Therefore, review the status of the defense in depth recommendations that apply to your specific deployment and align as needed. Especially the measures on the network layer to prevent accessibility from other network segments.
Mitigationwago_psirt
1. Use general security best practices to protect systems from local and network attacks. 2. Do not allow direct access to the device from untrusted networks. 3. Update to the latest firmware according to the table in chapter solutions. 4. Disable the DHCP, DNS and the FTP port 21. 5. Industrial control systems (ICS) should not be directly accessible from the Internet, but should be protected by consistently applying the defense-in-depth strategy. The BSI provides general information on securing ICS in the ICS Compendium [BSI2013] and on the official BSI website [BSI2021]. For fieldbus coupler: - 750-331 - 750-352/xxx-xxx For PLCs: - 750-829 - 750-831/xxx-xxx - 750-852 - 750-880/xxx-xxx - 750-881 - 750-889 The listed fieldbus coupler and PLCs above are based on Nucleus V1 RTOS. At the moment there are no updates for this version available. Due to this reason WAGO recommends according to the recommendations of the BSI to implement the following measures: 1. Enforce segmentation controls and proper network hygiene to reduce the risk of vulnerable devices. Restrict external communication paths and isolate vulnerable devices in zones as a mitigating measure. 2. Ensure DHCP responses from non-authorized servers are blocked or discarded. 3. Monitor network traffic for anomalies and discard invalid packets. 4. Disable or block FTP, DHCP, DNS especially on critical network segments 5. Please check regularly https://certvde.com/de/ for an update of this Advisory.

PLUSCONTROL devices are typically located in a separate LAN segment of energy transmission solutions, where an attacker could use these vulnerabilities to disrupt SER messages or Trace functionalities. Therefore, review the status of the defense in depth recommendations that apply to your specific deployment and align as needed. Especially the measures on the network layer to prevent accessibility from other network segments.
