Detailsinfo

A vulnerability classified as critical was found in Schneider Electric SoMachine Basic and Modicon TM221CE16R (SCADA Software) (the affected version unknown). Affected by this vulnerability is an unknown part of the component Project Protection Feature. The manipulation as part of a XML File leads to a hard-coded credentials vulnerability (Password). The CWE definition for the vulnerability is CWE-798. The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. As an impact it is known to affect confidentiality. The summary by CVE is:

Schneider Electric SoMachine Basic 1.4 SP1 and Schneider Electric Modicon TM221CE16R 1.3.3.3 devices have a hardcoded-key vulnerability. The Project Protection feature is used to prevent unauthorized users from opening an XML protected project file, by prompting the user for a password. This XML file is AES-CBC encrypted; however, the key used for encryption (SoMachineBasicSoMachineBasicSoMa) cannot be changed. After decrypting the XML file with this key, the user password can be found in the decrypted data. After reading the user password, the project can be opened and modified with the Schneider product.
