The result of this vulnerability, DLL substitution, could allow the transference of malicious code to the controller.

A Environment (CWE-2) vulnerability exists in SoMachine Basic, all versions, and Modicon M221(all references, all versions prior to firmware V1.10.0.0) which could cause remote launch of SoMachine Basic when sending crafted ethernet message.

An Incorrect Default Permissions (CWE-276) vulnerability exists in SoMachine Basic, all versions, and Modicon M221(all references, all versions prior to firmware V1.10.0.0) which could cause unauthorized access to SoMachine Basic resource files when logged on the system hosting SoMachine Basic.

An Environment (CWE-2) vulnerability exists in SoMachine Basic, all versions, and Modicon M221(all references, all versions prior to firmware V1.10.0.0) which could cause cycle time impact when flooding the M221 ethernet interface while the Ethernet/IP adapter is activated.

A Insufficient Verification of Data Authenticity (CWE-345) vulnerability exists in the Modicon M221, all versions, which could cause a change of IPv4 configuration (IP address, mask and gateway) when remotely connected to the device.

Schneider Electric SoMachine Basic prior to v1.6 SP1 suffers from an XML External Entity (XXE) vulnerability using the DTD parameter entities technique resulting in disclosure and retrieval of arbitrary data on the affected node via out-of-band (OOB) attack. The vulnerability is triggered when input passed to the xml parser is not sanitized while parsing the xml project/template file.
