Moxa AIG-302 ThingsPro Edge has a hard-coded key flaw, CVE-2026-109813 (CVSS 8.1). CISA also flagged 6 local DoS CVEs in HMS PEAK-System PCAN drivers. CISA https://www.cisa.gov/news-events/ics-advisories/icsa-26-293-03 #ICS
A hard-coded cryptographic key in Moxa AIG-302 ThingsPro Edge firmware (CVE-2026-109813) lets unauthenticated adjacent attackers recover private key material and compromise device communications — no credentials required. Combined with a missing authorization flaw on the /api/v1/secrets/ API (CVE-2026-109812), attackers can escalate access and extract secrets across ICS gateways in manufacturing, energy, and water systems. In OT environments where trust boundaries rely on shared key infrastructure, compromised cryptographic material can enable lateral movement that bypasses conventional security controls entirely. #ThreatIntel #ICS 🔗 Full TRC analysis: https://aviatrix.ai/threat-research-center/icsa-26-293-03-moxa-aig-302-thingspro-edge-cve-2026-109812-cve-2026-109813
