CVE-2025-25069
📋 TL;DR
A Cross-Protocol Scripting vulnerability in Apache Kvrocks allows HTTP requests to be interpreted as valid RESP (Redis Serialization Protocol) commands. This enables attackers to perform unauthorized database operations when chained with SSRF attacks. All Apache Kvrocks users running versions up to 2.11.0 are affected.
💻 Affected Systems
- Apache Kvrocks
📦 What is this software?
Kvrocks by Apache
⚠️ Risk & Real-World Impact
Worst Case
Attackers could execute arbitrary database commands leading to data theft, data corruption, or complete database compromise when combined with SSRF.
Likely Case
Unauthorized database operations including data retrieval, modification, or deletion through SSRF vectors.
If Mitigated
Limited impact with proper network segmentation and access controls preventing external SSRF exploitation.
🎯 Exploit Status
Similar to CVE-2016-10517 in Redis; exploitation requires SSRF vector to send crafted requests.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.11.1
Vendor Advisory: https://lists.apache.org/thread/gbxv9gpsskmdzg6z48zm3tvo8cyo9v3t
Restart Required: Yes
Instructions:
1. Download Apache Kvrocks 2.11.1 from official sources. 2. Stop the Kvrocks service. 3. Replace the binary with the patched version. 4. Restart the Kvrocks service. 5. Verify the version is 2.11.1 or higher.
🔧 Temporary Workarounds
Network Segmentation
linuxRestrict network access to Kvrocks service to only trusted applications and networks.
iptables -A INPUT -p tcp --dport 6666 -s trusted_ip_range -j ACCEPT
iptables -A INPUT -p tcp --dport 6666 -j DROP
SSRF Protection
allImplement SSRF protections in applications that could send requests to Kvrocks.
🧯 If You Can't Patch
- Implement strict network access controls to limit Kvrocks service exposure
- Deploy web application firewalls or reverse proxies to filter malicious HTTP/RESP hybrid requests
🔍 How to Verify
Check if Vulnerable:
Check if running Apache Kvrocks version 2.11.0 or earlier. If version is <=2.11.0 and service is accessible, assume vulnerable.Check Version:
redis-cli -p 6666 INFO | grep kvrocks_versionVerify Fix Applied:
Verify the running version is 2.11.1 or higher using the version check command.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP-like requests to Kvrocks port
- Database operations from unexpected sources
Network Indicators:
- HTTP requests containing 'Host:' or 'POST' sent to Kvrocks port (default 6666)
- SSRF attempts to internal Kvrocks service
SIEM Query:
source_port=6666 AND (http_user_agent OR http_host OR http_method)
