CVE-2024-26580
📋 TL;DR
This CVE describes a deserialization vulnerability in Apache InLong that allows attackers to read arbitrary files from the server. The vulnerability affects Apache InLong versions 1.8.0 through 1.10.0. Attackers can exploit this by sending specially crafted payloads to vulnerable instances.
💻 Affected Systems
- Apache InLong
📦 What is this software?
Inlong by Apache
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise leading to data exfiltration, privilege escalation, and potential lateral movement within the network.
Likely Case
Unauthorized reading of sensitive files including configuration files, credentials, and application data from the server.
If Mitigated
Limited impact with proper network segmentation and access controls preventing exploitation attempts.
🎯 Exploit Status
The vulnerability allows file reading via deserialization attacks, which typically have low exploitation complexity once the payload is known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.11.0
Vendor Advisory: https://lists.apache.org/thread/xvomf66l58x4dmoyzojflvx52gkzcdmk
Restart Required: Yes
Instructions:
1. Backup your current configuration and data. 2. Download Apache InLong 1.11.0 from the official Apache website. 3. Stop the InLong service. 4. Replace the installation with version 1.11.0. 5. Restore configuration and data. 6. Start the service and verify functionality.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict network access to InLong instances to only trusted sources
iptables -A INPUT -p tcp --dport [INLONG_PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [INLONG_PORT] -j DROP
🧯 If You Can't Patch
- Implement strict network segmentation to isolate InLong instances from untrusted networks
- Deploy web application firewall (WAF) rules to detect and block deserialization attempts
🔍 How to Verify
Check if Vulnerable:
Check the InLong version by examining the application logs or configuration files for version information. Versions 1.8.0 through 1.10.0 are vulnerable.Check Version:
grep -i version /path/to/inlong/config/*.properties 2>/dev/null || cat /path/to/inlong/logs/*.log | grep -i versionVerify Fix Applied:
Verify the installed version is 1.11.0 or later by checking the application version in logs or configuration.📡 Detection & Monitoring
Log Indicators:
- Unusual deserialization attempts in application logs
- Error messages related to file access or serialization failures
- Requests with unusual payloads or content types
Network Indicators:
- Unusual traffic patterns to InLong endpoints
- Requests containing serialized object data
SIEM Query:
source="inlong.logs" AND ("deserialization" OR "serialization" OR "FileNotFoundException" OR "IOException")
