Vulnerability from github – Published: 2022-05-24 19:06 – Updated: 2022-07-13 00:01

Details

The blockchain node in FISCO-BCOS V2.7.2 may have a bug when dealing with unformatted packet and lead to a crash. A malicious node can send a packet continuously. The packet is in an incorrect format and cannot be decoded by the node correctly. As a result, the node may consume the memory sustainably and crash. More details are shown at: https://github.com/FISCO-BCOS/FISCO-BCOS/issues/1951

Severity

7.5 (High)

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.
