# CTI-Bench: Vulnerability Severity Prediction (VSP)

## Dataset Description

This dataset contains **1,000 CVE descriptions** with corresponding CVSS v3.1 base scores. It evaluates a model's ability to assess vulnerability severity and generate proper CVSS vector strings.

## Dataset Structure

Each example contains:
- **url**: CVE URL (typically from nvd.nist.gov)
- **description**: CVE description detailing the vulnerability
- **prompt**: Full instruction prompt explaining CVSS v3.1 metrics
- **cvss_vector**: Ground truth CVSS v3.1 vector string (e.g., "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H")
- **task_type**: Always "vulnerability_severity_prediction"

## CVSS v3.1 Metrics

The dataset covers all base metrics:
- **AV** (Attack Vector): Network (N), Adjacent (A), Local (L), Physical (P)
- **AC** (Attack Complexity): Low (L), High (H)
- **PR** (Privileges Required): None (N), Low (L), High (H)
- **UI** (User Interaction): None (N), Required (R)
- **S** (Scope): Unchanged (U), Changed (C)
- **C** (Confidentiality): None (N), Low (L), High (H)
- **I** (Integrity): None (N), Low (L), High (H)
- **A** (Availability): None (N), Low (L), High (H)

## Usage

```python
from datasets import load_dataset

# Load the dataset
dataset = load_dataset("tuandunghcmut/cti_bench_vsp")

# Access a sample
sample = dataset['train'][0]
print(f"CVE: {sample['description']}")
print(f"CVSS Vector: {sample['cvss_vector']}")
```

## Example

**CVE Description:** In the Linux kernel through 6.7.1, there is a use-after-free in cec_queue_msg_fh, related to drivers/media/cec/core/cec-adap.c...

**CVSS Vector:** CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
