Siemens Multiple Vulnerabilities in SCALANCE Products
By injecting code to specific configuration options for OpenVPN, an attacker could execute arbitrary code with elevated privileges. Affected devices use a weak encryption scheme to encrypt the debug zip file. This could allow an authenticated attacker to decrypt the contents of the file and retrieve debug information about the system. Affected devices store the CLI user passwords encrypted in flash memory. Attackers with physical access to the device could retrieve the file and decrypt the CLI user passwords. Affected devices do not check the TFTP blocksize correctly. This could allow an authenticated attacker to read from an uninitialized buffer that potentially contains previously allocated data. Affected devices do not properly process CLI commands after a user forcefully quitted the SSH connection. This could allow an authenticated attacker to make the CLI via SSH or serial  interface irresponsive.
