## Description

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.
