A newly disclosed critical vulnerability, CVE-2025-7742, is putting hundreds of LG Innotek LNV5110R security cameras at risk around the world—including within critical infrastructure. This high-severity authentication bypass flaw allows remote attackers to gain full administrative control without credentials, giving them access to live camera feeds, the ability to disable or disrupt device functionality, and the opportunity to pivot deeper into internal networks.
The most alarming detail? LG Innotek has confirmed it will not release a patch, as the affected camera model has officially reached its end-of-life (EOL) status. Security researcher Souvik Kandar uncovered the vulnerability, which is now being highlighted by major security bodies like CISA. With over 1,300 internet-exposed devices still active, the risk of exploitation is very real—and immediate.
This episode unpacks the technical details of the vulnerability, the wider dangers of unpatched EOL devices, and the pressing need for network segmentation, Zero Trust access controls, and proactive EOL management policies. We examine how remote code execution (RCE) enables threat actors to escalate privileges, maintain persistence, and launch further attacks—all starting with an unpatched IoT device.
From the failure to patch, to poor lifecycle management, to the broader lessons in infrastructure security, this is more than just a flaw in one device—it’s a case study in how old tech becomes a new threat.
