CVE-2024-52577
📋 TL;DR
This vulnerability allows remote code execution on Apache Ignite servers by bypassing class serialization filters. Attackers can craft malicious messages that, when deserialized, execute arbitrary code on the server. Affects Apache Ignite versions 2.6.0 through 2.16.x.
💻 Affected Systems
- Apache Ignite
📦 What is this software?
Ignite by Apache
⚠️ Risk & Real-World Impact
Worst Case
Full server compromise leading to data theft, lateral movement, and persistent backdoor installation.
Likely Case
Remote code execution with the privileges of the Ignite process, potentially leading to data exfiltration or service disruption.
If Mitigated
Limited impact if network access is restricted and proper input validation is in place.
🎯 Exploit Status
Requires knowledge of Ignite's serialization protocol and crafting malicious messages, but no authentication is needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.17.0
Vendor Advisory: https://lists.apache.org/thread/1bst0n27m9kb3b6f6hvlghn182vqb2hh
Restart Required: Yes
Instructions:
1. Download Apache Ignite 2.17.0 or later from the official website. 2. Stop all Ignite nodes. 3. Replace the Ignite JAR files with the patched version. 4. Restart all Ignite nodes. 5. Verify the version is 2.17.0 or higher.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to Ignite endpoints using firewalls or network security groups.
Disable Vulnerable Endpoints
allConfigure Ignite to disable or restrict access to endpoints that accept serialized objects if not needed.
🧯 If You Can't Patch
- Implement strict network controls to limit access to Ignite servers to trusted IPs only.
- Monitor network traffic for unusual patterns or attempts to send crafted messages to Ignite endpoints.
🔍 How to Verify
Check if Vulnerable:
Check the Apache Ignite version. If it's between 2.6.0 and 2.16.x inclusive, it's vulnerable.Check Version:
java -jar ignite-core.jar --versionVerify Fix Applied:
Verify the installed version is 2.17.0 or higher and that class serialization filters are properly enforced.📡 Detection & Monitoring
Log Indicators:
- Unexpected deserialization errors
- Stack traces containing suspicious class names
- Unusual network connections to Ignite ports
Network Indicators:
- Unusual traffic patterns to Ignite endpoints (default ports 11211, 47100, 47500, 49112)
- Crafted network packets targeting Ignite serialization protocols
