CIRCL/vulnerability-severity-classification-chinese-macbert-base

VLAI: A RoBERTa-Based Model for Automated Vulnerability Severity Classification (Chinese Text)

This model is a fine-tuned version of hfl/chinese-macbert-base on the dataset CIRCL/Vulnerability-CNVD.

For more information, visit the Vulnerability-Lookup project page or the ML-Gateway GitHub repository, which demonstrates its usage in a FastAPI server.

It achieves the following results on the evaluation set:

• Loss: 0.5994
• Accuracy: 0.7900

How to use

You can use this model directly with the Hugging Face transformers library for text classification:

from transformers import pipeline

classifier = pipeline(
    "text-classification",
    model="CIRCL/vulnerability-severity-classification-chinese-macbert-base"
)

# Example usage for a Chinese vulnerability description
description_chinese = "TOTOLINK A3600R是中国吉翁电子（TOTOLINK）公司的一款6天线1200M无线路由器。TOTOLINK A3600R存在缓冲区溢出漏洞，该漏洞源于/cgi-bin/cstecgi.cgi文件的UploadCustomModule函数中的File参数未能正确验证输入数据的长度大小，攻击者可利用该漏洞在系统上执行任意代码或者导致拒绝服务。"
result_chinese = classifier(description_chinese)
print(result_chinese)
# Expected output example: [{'label': '高', 'score': 0.9802}]
