CVE-2023-38024
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSpotCam Co., Ltd. SpotCam FHD 2’s hidden Telnet function has a vulnerability of using hard-coded Telnet credentials. An remote unauthenticated attacker can exploit this vulnerability to access the system to perform arbitrary system operations or disrupt service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe SpotCam FHD 2 camera firmware contains a hidden Telnet service that is accessible using hard-coded credentials. An unauthenticated remote attacker can connect to this Telnet service using the static credentials embedded in the firmware, gaining full system access to execute arbitrary commands or cause service disruption.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify firmware versionAccess the camera's web interface, administrative settings, or use the vendor's discovery tool to retrieve the current firmware version. Alternatively, check via the device's API or UPNP information if available.Affected if The firmware version is lower than 1.0039 (e.g., 1.0038, 1.0037, etc.)
-
Verify Telnet port accessibilityFrom a workstation on the same network segment, run 'telnet <camera_ip> 23' or use nmap: 'nmap -p 23 <camera_ip>' to test if port 23 responds.Affected if Port 23 responds to connection attempts, indicating the Telnet service is exposed on the network.
-
Confirm Telnet service responds to loginAttempt to connect to port 23 using the hard-coded credentials found in firmware images (embedded strings in firmware dumps). Note: Do not actually log in to production devices; this check confirms the service accepts authentication.Affected if The Telnet service accepts connections and prompts for credentials, confirming the hidden service is active.
-
Review network exposureCheck router, firewall, or VLAN configurations to determine if the camera's IP is reachable from untrusted network segments or the internet. Verify whether port 23 traffic is blocked at network boundaries.Affected if The camera is reachable from outside its intended management network, or port 23 traffic is not blocked at the network perimeter.
A user is affected if their device runs firmware version below 1.0039 AND the hidden Telnet service on port 23 is exposed and accessible on the network.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data1.0039
Apply vendor firmware updates when available; meanwhile, isolate the device on a restricted network segment or VLAN, block outbound and inbound Telnet traffic (port 23) at the network perimeter, and disable the device if Telnet cannot be turned off.
