Siprotec 5 7Sj81 Cp100
Monthly
Unrestricted file upload via the DIGSI 5 engineering protocol in Siemens SIPROTEC 5 protective relays enables authenticated, high-privileged users on an adjacent network to upload malicious configuration files, causing denial of service or potentially achieving code execution on the affected device. All hardware variants (CP050/CP100/CP150/CP200/CP300) across more than 60 distinct SIPROTEC 5 model lines are affected, with no patched firmware version available. No public exploit identified at time of analysis, but the presence of RCE and DoS tags alongside a confirmed CWE-434 root cause makes this a meaningful operational technology (OT) risk in poorly segmented substation environments.
A vulnerability has been identified in SIPROTEC 5 6MD84 (CP300) (All versions < V11.0), SIPROTEC 5 6MD85 (CP200) (All versions), SIPROTEC 5 6MD85 (CP300) (All versions >= V7.80 < V11.0), SIPROTEC 5. Rated medium severity (CVSS 6.9), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
