In OpenWrt LuCI git-20.x, remote unauthenticated attackers can retrieve the list of installed packages and services. NOTE: the vendor disputes the significance of this report because, for instances reachable by an unauthenticated actor, the same information is available in other (more complex) ways, and there is no plan to restrict the information further

Security readout for executives and security teams

Plain-English summary

This issue is an information leak in OpenWrt LuCI git-20.x. If LuCI is reachable without login, outsiders may learn installed packages and services. That can help reconnaissance, but the vendor disputes its significance and the source bundle names no direct compromise path.

Executive priority

Treat this as a low-priority hardening item unless LuCI is internet-exposed. The main business risk is reconnaissance against network devices, not confirmed compromise. Prioritize reducing management-plane exposure.

Technical view

CVE-2020-10871 describes unauthenticated retrieval of installed package and service listings from OpenWrt LuCI git-20.x. The record provides no CVSS, CWE, CPE, patch, or confirmed fixed version. Vendor comments reportedly state similar information is obtainable otherwise and there is no plan to further restrict it.

Likely exposure

Exposure is most relevant where OpenWrt LuCI git-20.x is reachable by unauthenticated users, especially from the internet or untrusted networks. The bundle does not identify broader affected versions or CPEs.

Exploitation context

The bundle supports unauthenticated information retrieval, not code execution, authentication bypass, or active exploitation. KEV is false, and no cited source states exploitation in the wild.

Researcher notes

Evidence is limited and disputed by the vendor. Avoid overstating severity: the record lacks CVSS, CPEs, exploit evidence, and a named fix. Focus validation on unauthenticated reachability and whether disclosed package/service data materially increases local risk.

Mitigation direction

  • Inventory OpenWrt systems running LuCI git-20.x.
  • Do not expose LuCI management interfaces to untrusted networks.
  • Restrict LuCI access using firewall rules, VPN, or trusted admin networks.
  • Review OpenWrt LuCI guidance and linked issue discussions for vendor position.
  • Monitor LuCI access logs for unauthenticated reconnaissance activity.

Validation and detection

  • Confirm whether any LuCI instance is reachable without authentication.
  • Check OpenWrt and LuCI versions on managed devices.
  • Verify management interfaces are not exposed to the public internet.
  • Review access logs for unauthenticated requests to LuCI package or service views.
  • Document accepted risk if exposure remains by design.
