CVE-2024-10264
📋 TL;DR
CVE-2024-10264 is an HTTP request smuggling vulnerability in netease-youdao/qanything version 1.4.1 that allows attackers to bypass security controls by exploiting differences in how HTTP requests are interpreted between proxies and servers. This can lead to unauthorized access, session hijacking, and data leakage. Organizations using qanything version 1.4.1 are affected.
💻 Affected Systems
- netease-youdao/qanything
📦 What is this software?
Qanything by Youdao
⚠️ Risk & Real-World Impact
Worst Case
Attackers achieve arbitrary code execution, gain full system control, and exfiltrate sensitive data from the qanything application and underlying infrastructure.
Likely Case
Attackers bypass authentication, hijack user sessions, access unauthorized data, and potentially manipulate application functionality.
If Mitigated
With proper network segmentation and WAF rules, impact is limited to potential service disruption and limited data exposure.
🎯 Exploit Status
Exploitation requires understanding of HTTP request smuggling techniques and ability to craft malicious requests.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.4.2 or later
Vendor Advisory: https://huntr.com/bounties/988247d5-fd60-4d85-845a-e867d62c0d02
Restart Required: Yes
Instructions:
1. Update qanything to version 1.4.2 or later. 2. Restart the qanything service. 3. Verify the update was successful.
🔧 Temporary Workarounds
WAF Rule Implementation
allConfigure WAF to detect and block HTTP request smuggling attempts
Proxy Configuration Hardening
allEnsure all proxies in the traffic path are configured to reject ambiguous HTTP requests
🧯 If You Can't Patch
- Isolate qanything instances behind dedicated proxies with strict HTTP parsing
- Implement network segmentation to limit potential lateral movement
🔍 How to Verify
Check if Vulnerable:
Check if running qanything version 1.4.1. Use HTTP request smuggling testing tools against the application.Check Version:
Check qanything configuration files or deployment manifests for version informationVerify Fix Applied:
Verify qanything version is 1.4.2 or later. Test with HTTP request smuggling tools to confirm vulnerability is patched.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP request patterns
- Multiple requests with same connection
- Malformed HTTP headers
Network Indicators:
- HTTP requests with conflicting Content-Length and Transfer-Encoding headers
- Unexpected request smuggling patterns
SIEM Query:
source="qanything" AND (http.request.header="Transfer-Encoding" OR http.request.header="Content-Length") AND event.action="anomaly"
