Details

Shenzhen Tenda F3 Wireless Router firmware V12.01.01.55_multi contains a clickjacking vulnerability in the web-based administrative interface. The interface does not set the X-Frame-Options header, allowing attacker-controlled sites to embed administrative pages in an iframe and trick an authenticated administrator into unintended interactions that may result in unauthorized configuration changes.

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.
