CVE-2022-50932: Kyocera Command Center RX ECOSYS M2035dn - Directory Traversal File Disclosure (Unauthenticated)

Kyocera Command Center RX ECOSYS M2035dn contains a directory traversal vulnerability that allows unauthenticated attackers to read sensitive system files by manipulating file paths under the /js/ path. Attackers can exploit the issue by sending requests like /js/../../../../.../etc/passwd%00.jpg (null-byte appended traversal) to access critical files such as /etc/passwd and /etc/shadow.

Security readout for executives and security teams

Plain-English summary

This issue affects Kyocera Command Center RX on ECOSYS M2035dn devices. An unauthenticated attacker may read sensitive files from the device through a path traversal flaw. The main business risk is exposure of credentials or system data from printers/MFPs, especially if their web interfaces are reachable from untrusted networks.

Executive priority

Prioritize review if Kyocera ECOSYS M2035dn management interfaces are exposed beyond trusted administrators. The issue is high severity because it requires no login and may disclose sensitive files. If exposure is internal-only and tightly restricted, handle through normal vulnerability management with network hardening.

Technical view

CVE-2022-50932 is a CWE-22 directory traversal file disclosure in Kyocera Command Center RX for ECOSYS M2035dn. The reported flaw is reachable over the network without authentication and abuses path handling under the web interface’s /js/ path. CVSS v4 is 8.7, with high confidentiality impact and no integrity or availability impact reported.

Likely exposure

Organizations with ECOSYS M2035dn devices exposing Command Center RX are the relevant population. Internet exposure or broad internal access increases risk. The provided sources do not identify other Kyocera models or confirmed vulnerable firmware versions beyond ECOSYS M2035dn.

Exploitation context

A public ExploitDB entry and VulnCheck advisory exist, indicating public technical knowledge. The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Treat exploitability as practical, but do not assume observed exploitation without local telemetry.

Researcher notes

Evidence is strongest for unauthenticated file disclosure on ECOSYS M2035dn Command Center RX. Public exploit reference exists, but the provided bundle does not include a Kyocera security advisory, patched version, or broader affected model list. Avoid extrapolating impact to other Command Center RX devices without separate evidence.

Mitigation direction

  • Identify ECOSYS M2035dn devices running Command Center RX.
  • Remove printer web management interfaces from internet exposure.
  • Restrict Command Center RX access to trusted admin networks only.
  • Check Kyocera guidance for firmware updates or vendor-recommended mitigations.
  • Apply available vendor updates after testing.
  • Monitor device logs and perimeter logs for traversal attempts.

Validation and detection

  • Inventory Kyocera ECOSYS M2035dn assets and management IPs.
  • Confirm whether Command Center RX is enabled and reachable.
  • Review exposure from internet, VPN, guest, and user subnets.
  • Check firmware and configuration against Kyocera documentation.
  • Search logs for parent-directory traversal patterns targeting the web interface.
  • Document compensating controls if no vendor fix is available.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
