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.

  • SSA-097786SSA-097786: Insertion of Sensitive Information into Log File Vulnerability in SINUMERIK systems2024-09-10csaf · siemens_psirtDE

    SINUMERIK systems, that have been provisioned with Create MyConfig (CMC), are affected by a Insertion of Sensitive Information into Log File vulnerability. When using a CMC package on a NCU or on an IPC the password used in the CMC package or typed in manually during package execution is traced on the machine to the file uptrace.out. This could allow a local authenticated user with low privileges to read that password and use it to impersonate a user with higher privileges. Siemens has released new versions for the affected products and recommends to update to the latest versions.
