Vulnerability from variot
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. Schneider Electric SoMachine Basic and Modicon Contains a vulnerability in the use of hard-coded credentials.Information is obtained, information is altered, and service operation is disrupted (DoS) An attack may be carried out. The former is a programming and debugging interface for all components on the control platform; the latter is a programmable controller. An attacker could exploit the vulnerability to open and modify protected project files with Schneider's products. A remote attacker may leverage this issue to gain root access to the affected system
