Critical RCE Flaw in Industrial Video & Control Longwatch Threatens Global OT Networks
In December 2025, a critical remote code execution vulnerability (CVE-2025-13658) was discovered in Industrial Video & Control’s Longwatch systems (versions 6.309 to 6.334). An unauthenticated attacker could exploit a lack of access controls and code signing via an exposed HTTP endpoint, gaining SYSTEM-level privileges across vulnerable energy and water infrastructure deployments worldwide. This exploitation method requires minimal technical expertise and impacts operational technology (OT) integrity in sectors fundamental to public safety. This vulnerability exemplifies persistent gaps in OT device security and comes amid heightened global concerns around the security of essential infrastructure. With regulatory scrutiny and sophistication of attacker tactics increasing, organizations must urgently address privilege escalation routes and remote code execution exposures within their ICS/SCADA environments.
