Technical Description
A vulnerability has been identified in SINAMICS G220 V6.4 (All versions < V6.4 HF2), SINAMICS S200 V6.4 (All versions < V6.4 HF7), SINAMICS S210 V6.4 (All versions < V6.4 HF2). The affected devices allow a factory reset to be executed without the required privileges due to improper privilege management as well as manipulation of configuration data because of leaked privileges of previous sessions. This could allow an unauthorized attacker to escalate their privileges.
Remediation
Check the references section for vendor advisories and patches from siemens. Update sinamics_g220_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
