port8900/TCP↗

→CVE-2022-30230 allows unauthenticated remote creation of administrative users via privileged API functions on SICAM GridEdge (all versions < v2.6.6); monitor for unauthenticated POST/PUT requests to the GridEdge API on port 8900/TCP that result in new user creation. ↗
→Alert on any inbound unauthenticated connections to port 8900/TCP on SICAM GridEdge devices, especially from untrusted or external network segments. ↗
→CVE-2022-30230 carries a CVSS v3 score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H), indicating fully remote, no-auth, no-interaction exploitation — treat any anomalous admin account creation on GridEdge as high-priority. ↗

·All four SICAM GridEdge product variants (Essential ARM, Essential Intel, Essential with GDS ARM, Essential with GDS Intel) are affected for all versions prior to v2.6.6; scope detection broadly across all variants. ↗
·No known public exploits specifically target this vulnerability at time of advisory publication, but the attack complexity is low and no authentication is required. ↗
