CVE-2025-7742 LG Innotek CVE debrief

CVE-2025-7742 is a publicly disclosed authentication vulnerability in LG Innotek LNV5110R camera firmware. According to the CISA CSAF advisory, a malicious actor may upload an HTTP POST request to the device’s non-volatile storage, which may lead to remote code execution with administrator-level command execution. LG notes the product is end-of-life and can no longer be patched, so defenders should focus on isolation, access restriction, and replacement planning.

Who should care

Organizations operating LG Innotek LNV5110R cameras, especially environments that expose device management interfaces to broader networks or rely on legacy/end-of-life equipment, should treat this as a priority review item. Network defenders and asset owners responsible for camera fleets, site security systems, and industrial/operational environments that use the device should assess exposure and compensating controls.

Technical summary

The advisory describes an authentication weakness in LG Innotek LNV5110R firmware. It allows a malicious actor to submit an HTTP POST request that reaches the device’s non-volatile storage, and the impact may include remote code execution that runs arbitrary commands at administrator privilege level. The provided CVSS v3.1 vector is AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L, with a score of 7.0 (High).

Defensive priority

High: the issue can enable network-based admin-level command execution, and the vendor notes the affected product is end-of-life with no patch path available.

Recommended defensive actions

  • Identify whether any LG Innotek LNV5110R devices are deployed, including legacy or rarely used units.
  • Remove or tightly restrict network access to device management interfaces; prefer ACLs, VPN-only administration, or isolated management segments.
  • Place affected devices behind segmentation controls and limit exposure to trusted management hosts only.
  • Treat the device as unpatchable unless the vendor provides a specific supported remediation path; plan replacement or retirement.
  • Review available logs and network telemetry for unusual HTTP POST activity or unexpected management access to the device.
  • Follow CISA ICS recommended practices and defense-in-depth guidance for containment and access control.

Evidence notes

CISA’s CSAF advisory for ICSA-25-205-04, published and last modified on 2025-07-25, identifies CVE-2025-7742 as affecting LG Innotek LNV5110R products (vers:all/*). The source description states that an authentication vulnerability may permit HTTP POST upload to non-volatile storage and lead to remote code execution with administrator privileges. The advisory metadata also supplies CVSS v3.1 vector AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L and a score of 7.0. Remediation notes state the product is end-of-life and can no longer be patched, with LG Security Center referenced for further guidance.
