Description
The use of
hard-coded cryptographic key vulnerability has been identified in the mesh
functionality of Deco XE75 v3, XE5300 v3.6 and WE10800 v3.6.
A shared RSA-512 mesh group private key is present in the affected
firmware and is used by the mesh protocol for node authentication. An attacker who obtains the firmware image
and has local network access may be able to authenticate as a mesh node without
possessing a device-specific credential.
Successful
exploitation may allow an unauthenticated adjacent attacker to impersonate a
trusted mesh node and bypass mesh node authentication, which may permit unauthorized
changes to device or mesh configuration, affecting confidentiality, integrity
and availability.
