Traccar WebSocket Origin Validation Missing Leading to CSWSH and Location Leakage

Thinking Process: 1. Analyze the Request: Task: Translate a Chinese vulnerability intelligence summary into English. Role: Professional translator specializing in cybersecurity. Constraint 1: Maintain all Markdown formatting intact. Constraint 2: Do not add any introductory or concluding remarks. Input: A structured text about a vulnerability (CWE-1385, Traccar/Jetty related). Output: English translation only. 2. Analyze the Input Text: Title: (Critical Vulnerability Information) Section 1: (Overview) -> Vulnerability Type: CWE-1385 (Missing Origin Validation in WebSocket) -> Severity: High Section 2: (Scope of Impact / Affected Scope) -> Affected Version: 6.11.1 -> Fixed Version: None Section 3: (Vulnerability Details) /api/socket` /api/socket 根本原因: Jetty 服务器配置或 WebSocket 处理程序没有检查 Origin 头是否匹配主机域。允许任意 Origin（如 或 ）。 http://hacker.com null 影响 实时跟踪: 攻击者可通过实时 WebSocket 流获取所有追踪资产的确切地理位置。 设备指纹: 泄露敏感设备元数据，包括 deviceId、协议（例如 osmand）和 batteryLevel。 漏洞利用范围: 任何被诱骗访问恶意网站且已登录 Traccar 的用户，其-tracking 数据将被即时暴露，从而绕过应用的访问控制机制。 应对措施 检查 Origin 头: 服务器应检查 HTTP 升级请求的 Origin 头。 白名单方法: 比较 Origin 值与受信域的严格白名单（如服务器自身的域和配置的协议）。 拒绝不可信数据: 如果 Origin 与白名单不匹配（或者根据安全策略是 null 或空），服务器必须立即拒绝连接（例如返回 HTTP 403）而不是升级到 WebSocket。 Python 漏洞利用脚本 通过带有恶意 Origin 头的握手请求模拟漏洞场景。 总结 此漏洞允许未授权的攻击者通过受害者被劫持的会话执行跨站 WebSocket 劫持（CSWSH）攻击，导致实时地理定位数据泄露以及设备数据的暴露。解决问题的关键在于严格实施 Origin 验证策略。 - /api/socket http://hacker.com /api/socket http://hacker.com null 其-tracking 数据 null Python Exploit Script - Simulates the vulnerability scenario via a handshake request with a malicious Origin header.

Impact Real-time Tracking: Attackers can obtain the exact geographical location of all tracked assets via real-time WebSocket streams. Device Fingerprinting: Leaks sensitive device metadata, including deviceId, protocol (e.g., osmand), and batteryLevel. Exploitation Scope: Tracking data of any user tricked into visiting a malicious website while logged into Traccar will be immediately exposed, bypassing the application's access control mechanisms. Mitigation Measures Check Origin Header: The server should check the Origin header of HTTP upgrade requests. Whitelist Approach: Compare the Origin value against a strict whitelist of trusted domains (e.g., the server's own domain and configured protocols). Reject Untrusted Data: If the Origin does not match the whitelist (or is null/empty according to security policy), the server must immediately reject the connection (e.g., return HTTP 403) instead of upgrading to WebSocket. Python Exploit Script Simulates the vulnerability scenario via a handshake request with a malicious Origin header. Summary This vulnerability allows unauthorized attackers to perform Cross-Site WebSocket Hijacking (CSWSH) attacks via hijacked victim sessions, leading to leakage of real-time geolocation data and exposure of device data. The key to resolving the issue lies in strictly implementing Origin validation policies.
