A vulnerability has been identified in SINUMERIK 828D V4 (All versions < V4.95 SP3), SINUMERIK 840D sl V4 (All versions < V4.95 SP3 in connection with using Create MyConfig (CMC) <= V4.8 SP1 HF6), SINUMERIK ONE (All versions < V6.23 in connection with using Create MyConfig (CMC) <= V6.6), SINUMERIK ONE (All versions < V6.15 SP4 in connection with using Create MyConfig (CMC) <= V6.6). Affected systems, that have been provisioned with Create MyConfig (CMC), contain a Insertion of Sensitive Information into Log File vulnerability. This could allow a local authenticated user with low privileges to read sensitive information and thus circumvent access restrictions.
Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information.
While logging all information may be helpful during development stages, it is important that logging levels be set appropriately before a product ships so that sensitive user data and system information are not accidentally exposed to potential attackers. Different log files may be produced and stored for:
