Title
Security Boundary Bypass via Routing Node Impersonation
Summary
A vulnerability has been identified where an attacker connecting to an access point as a standard wired or wireless client can impersonate a gateway by leveraging an address-based spoofing technique. Successful exploitation enables the redirection of data streams, allowing for the interception or modification of traffic intended for the legitimate network gateway via a Machine-in-the-Middle (MitM) position.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
