CVE-2020-35758: An issue was discovered on Libre Wireless LS9 LS1.5/p7040 devices.

An issue was discovered on Libre Wireless LS9 LS1.5/p7040 devices. There is a Authentication Bypass in the Web Interface. This interface does not properly restrict access to internal functionality. Despite presenting a password login page on first access, authentication is not required to access privileged functionality. As such, it's possible to directly access APIs that should not be exposed to an unauthenticated user.

Security readout for executives and security teams

Plain-English summary

Libre Wireless LS9 LS1.5/p7040 devices may show a login page but still allow unauthenticated users to reach privileged web-interface APIs. If the device management interface is reachable by untrusted users, this can undermine administrative access controls and expose internal device functions.

Executive priority

Treat this as urgent for any reachable device management interface. Prioritize isolation and vendor guidance checks before normal change windows if exposure extends beyond a tightly controlled admin network.

Technical view

CVE-2020-35758 is an authentication bypass in the LS9 web interface. The reported issue is improper restriction of internal functionality, allowing direct access to APIs that should require authentication. Public data does not provide CVSS, CWE, CPE, fixed versions, or patch status.

Likely exposure

Exposure is most likely where Libre Wireless LS9 LS1.5/p7040 device web interfaces are reachable from user networks, partner networks, or the internet. The source bundle does not prove internet-scale exposure.

Exploitation context

The CVE is not listed as CISA KEV in the supplied bundle. The cited description supports unauthenticated access to privileged APIs, but no active exploitation, public exploit use, or attacker campaign is cited.

Researcher notes

The public record is sparse: no CVSS, CWE, CPE, affected version range, fixed version, or remediation detail is supplied. Analysis should focus on asset confirmation, reachability, and whether privileged API access is actually gated by authentication.

Mitigation direction

  • Inventory Libre Wireless LS9 LS1.5/p7040 devices and management interfaces.
  • Restrict web-interface access to trusted administrative networks only.
  • Check Libre Wireless or advisory guidance for firmware updates or official mitigations.
  • Segment affected devices if no confirmed fix is available.
  • Monitor management-interface traffic for unexpected unauthenticated API access.

Validation and detection

  • Confirm whether LS9 LS1.5/p7040 devices exist in the environment.
  • Identify all networks that can reach each device web interface.
  • Verify management access requires authentication before privileged API functionality is exposed.
  • Review device logs and network telemetry for suspicious web-interface requests.
  • Document firmware versions and compare them with vendor or advisory guidance.
