The web interface on multiple Samsung Harman AMX N-Series devices allows directory listing for the /tmp/ directory, without authentication, exposing sensitive information such as the command history and screenshot of the file being processed. This affects N-Series N1115 Wallplate Video Encoder before 1.15.61, N-Series N1x22A Video Encoder/Decoder before 1.15.61, N-Series N1x33A Video Encoder/Decoder before 1.15.61, N-Series N1x33 Video Encoder/Decoder before 1.15.61, N-Series N2x35 Video Encoder/Decoder before 1.15.61, N-Series N2x35A Video Encoder/Decoder before 1.15.61, N-Series N2xx2 Video Encoder/Decoder before 1.15.61, N-Series N2xx2A Video Encoder/Decoder before 1.15.61, N-Series N3000 Video Encoder/Decoder before 2.12.105, and N-Series N4321 Audio Transceiver before 1.00.06.

Security readout for executives and security teams

Plain-English summary

Some Samsung Harman AMX N-Series AV-over-IP devices exposed their /tmp/ directory through the web interface without requiring login. That could reveal sensitive operational artifacts, including command history and screenshots of files being processed. This is primarily an information disclosure issue, but exposed AV infrastructure can still create security and privacy risk.

Executive priority

Treat this as a near-term infrastructure hygiene issue, especially where AV systems process sensitive meetings, presentations, or media. Prioritize internet-exposed or broadly reachable management interfaces first. Business urgency rises if these devices operate in executive, boardroom, security, or confidential production environments.

Technical view

CVE-2023-38523 is an unauthenticated directory listing flaw in the web interface of multiple Harman AMX N-Series encoder, decoder, transceiver, and wallplate models. Affected firmware is before the fixed versions listed in the CVE record, including 1.15.61, 2.12.105, and 1.00.06 depending on model.

Likely exposure

Exposure is likely limited to organizations using affected Harman AMX N-Series devices whose management web interfaces are reachable by users, internal networks, or the internet. The source bundle does not provide scan counts or internet exposure data.

Exploitation context

The source bundle states unauthenticated access to /tmp/ directory listings. CISA KEV status is false, and no provided source states active exploitation. Public disclosure exists, but the supplied evidence does not establish exploitation in the wild.

Researcher notes

Evidence is limited to CVE metadata and vendor firmware references. No CVSS, CWE, patch details beyond fixed firmware thresholds, or exploitation telemetry is provided. Avoid assuming code execution or persistence; analyze as unauthenticated sensitive information disclosure unless further vendor material says otherwise.

Mitigation direction

  • Identify all Harman AMX N-Series devices and firmware versions.
  • Update affected models to the vendor-listed fixed firmware or later.
  • Restrict web management interfaces to trusted administrative networks.
  • Remove internet exposure from AV device management interfaces.
  • Check Harman guidance for model-specific update instructions.

Validation and detection

  • Inventory device models against the affected N-Series list.
  • Confirm firmware is at or above the fixed version for each model.
  • Verify unauthenticated users cannot browse the /tmp/ directory.
  • Review logs for unexpected web access to device temporary paths.
  • Validate management access controls after firmware updates.
