# CVE-2025-5054 Vulnerability Detection Tool
A Python tool to check if your Ubuntu system is vulnerable to [CVE-2025-5054](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2025-5054), a race condition in Apport that allows local information disclosure. This tool performs a series of checks to determine your system's status and provides recommendations if you are affected.
---
## Features
- Detects if the system is running Ubuntu and extracts version information
- Checks if Apport is installed and determines its version
- Determines if the installed Apport version is vulnerable (≤ 2.32.0)
- Checks if Apport is configured as the core dump handler
- Verifies mitigation settings (e.g., suid_dumpable)
- Looks for common attack vectors (e.g., SUID/SGID unix_chkpwd)
- Provides a clear summary and actionable recommendations
---
## Requirements
- Python 3.12 or higher
- No external dependencies
---
## Installation
1. **Clone the repository:**
```bash
git clone https://github.com/daryllundy/cve-2025-5054
cd cve-2025-5054
```
2. **Create and activate a virtual environment using [uv](https://github.com/astral-sh/uv):**
```bash
uv venv
source .venv/bin/activate
```
---
## Usage
> **For best results, run as root (sudo) to allow all checks to complete.**
```bash
uv run cve_2025_5054_detector.py
```

DETECTION RESULTS
============================================================
[OS Check] INFO: Ubuntu 22.04 detected
[Apport Check] INFO: Apport version 2.32.0 installed
[Version Check] VULNERABLE: Version 2.32.0 is vulnerable
[Core Pattern] INFO: Apport is configured as core dump handler
[Mitigation] WARNING: suid_dumpable=1 (default, vulnerable)
[Attack Vector] INFO: unix_chkpwd found at /usr/sbin/unix_chkpwd (not SUID/SGID)
============================================================
SUMMARY
============================================================
[!] YOUR SYSTEM APPEARS TO BE VULNERABLE TO CVE-2025-5054
Recommended actions:
1. Update Apport to the latest version:
sudo apt update && sudo apt upgrade apport
2. As a temporary mitigation, disable SUID core dumps:
sudo sysctl fs.suid_dumpable=0
echo 'fs.suid_dumpable=0' | sudo tee -a /etc/sysctl.conf
3. Consider disabling Apport temporarily if updates are not available:
sudo systemctl stop apport.service
sudo systemctl disable apport.service
