Title
Unauthenticated Onboarding Connect NULL Pointer Dereference Denial of Service Vulnerability in TP-Link Tapo C120 & C200
Summary
Tapo C120 v1 and C200 v5
contain a NULL pointer dereference in the HTTPS onboarding connect request parser. The interface is reachable without
authentication after initial setup and does not validate that a password field
is present for certain authentication and encryption parameter combinations,
allowing a malformed request from the same local network to crash the HTTPS service
Successful exploitation may
temporarily make HTTPS management functions unavailable. Repeated malformed
requests may sustain the denial-of-service condition, and recovery may in some
cases require a device reboot.

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.
