CVE-2017-7462

Think of your IP camera like a small office door with a secret “employee shortcut” built in by the manufacturer. This vulnerability may allow outsiders to find and use that shortcut, reaching a hidden script the camera exposes in its web interface. In the worst case, an attacker could take control of the camera and use it to spy on your premises or disrupt your equipment.

This matters to you if you run or manage an Intellinet NFC-30ir IP camera (the affected product). The weakness is reachable over the network, and the conditions described for this issue indicate it does not require a normal login to be triggered. The biggest practical risk is whether your camera can be reached from the internet (for example, through remote access or port-forwarding); if it is not internet-reachable, the risk is much lower.

This is an AMBER issue because a public exploit is available, meaning attackers can likely use it without extensive effort. Even without confirmation of broad real-world exploitation in public advisories, you should treat internet-exposed cameras as high priority to contain immediately.

1. Confirm exposure (what to check)

• Identify all devices running Intellinet NFC-30ir firmware.
• Determine network paths:
  • From outside your network: test whether the camera responds on its web interface (or on any ports you have forwarded).
  • From your internal network: check whether any “remote access” feature is enabled.
• Check your firewall/router for inbound rules/port forwarding that point to the camera.

2. Determine whether you’re eligible for a fix

• Look for firmware updates from Intellinet for the NFC-30ir.
• Based on our findings, we did not find a specific fixed firmware version for CVE-2017-7462.

3. Containment steps (do these first if internet-reachable)

• Disable remote administration/access on the camera.
• Remove port forwarding rules so no inbound connections from the internet can reach the camera.
• If you must keep the camera reachable for legitimate reasons, restrict it:
  • Only from your office IP address ranges (if your business uses static IPs), and
  • Only on the minimum required ports.
• Place the camera on an isolated IoT network/VLAN/subnet so that a compromised camera can’t easily reach laptops, accounting systems, or shared storage.

4. Mitigation if no patch is available

• Since no specific patch information is available in the findings, plan for one of:
  • Device replacement with a model that has an available, documented security fix, or
  • A compensating control approach (strict network isolation plus blocking internet access).

5. What to monitor

• Camera/system logs for unexpected web access attempts to CGI endpoints.
• Network logs on your router/firewall for repeated inbound hits from unusual IPs.
• Unexpected changes in camera behavior (settings changes, reboots, or new users) — even if exploitation is possible, detection and response help limit damage.

CVE-2017-7462 is a high-severity vulnerability (backed by a public exploit) involving a vendor backdoor in the Intellinet NFC-30ir IP Camera. The issue allows a remote attacker to access a vendor-supplied CGI script located in the camera’s web directory. The trigger conditions in the provided scoring indicate it does not require prior authentication or user interaction.

Key findings we rely on:

• A public exploit exists (weaponization available), increasing the practical risk.
• No fix/patch information was found for this CVE in the provided sources, so remediation may require isolation and/or replacement.
• This CVE is not listed in CISA KEV based on the provided findings.

Operational meaning of “KEV” here: KEV is a list of vulnerabilities known to be exploited in the wild; since it is not listed in the provided findings, widespread confirmed exploitation is not established there. Therefore, urgency is driven mainly by the availability of a public exploit and the possibility of internet exposure.
