Affected Products


XING INC.
  • XING CPTrans-ME-X firmware versions prior to Ver 1.8.1.17

Impact

  • Unauthenticated OS command injection (CVE-2026-62928)
  • Sensitive system information exposure (CVE-2026-66840)
  • Anyone with knowledge of the credentials may log in to the affected device (CVE-2026-69657, CVE-2026-70403)
Solution

[Update the firmware]
At the time of this JVN advisory publishing, the developer provides the firmware update to narrow the attack surface:
  • the administrative port is disabled in the initial configuration
  • the set of commands available when logged in is limited to only those necessary for maintenance purposes
According to the developer, an update via FOTA (Firmware Over-The-Air) was implemented for the affected products in April 2026.
