Severity
Summary
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. The BluFi example bundled in ESP-IDF was vulnerable to memory overflows in two areas: Wi-Fi credential handling and Diffie–Hellman key exchange. This vulnerability is fixed in 5.4.1, 5.3.3, 5.1.6, and 5.0.9.

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.
