CVE-2023-43668
📋 TL;DR
CVE-2023-43668 is an authorization bypass vulnerability in Apache InLong that allows attackers to manipulate user-controlled parameters to bypass security checks for sensitive settings like autoDeserialize and allowLoadLocalInfile. This affects Apache InLong versions 1.4.0 through 1.8.0. Organizations using vulnerable versions of Apache InLong for data integration are at risk.
💻 Affected Systems
- Apache InLong
📦 What is this software?
Inlong by Apache
⚠️ Risk & Real-World Impact
Worst Case
Attackers could bypass critical security controls, potentially enabling remote code execution, data exfiltration, or complete system compromise by manipulating sensitive configuration parameters.
Likely Case
Attackers with access to the application could bypass authorization checks to modify sensitive settings, potentially leading to data exposure or privilege escalation.
If Mitigated
With proper network segmentation and access controls, impact would be limited to the InLong application scope rather than broader infrastructure.
🎯 Exploit Status
Exploitation requires some level of access to the application interface but the vulnerability itself is straightforward to exploit once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.9.0
Vendor Advisory: https://lists.apache.org/thread/16gtk7rpdm1rof075ro83fkrnhbzn5sh
Restart Required: Yes
Instructions:
1. Upgrade Apache InLong to version 1.9.0 or later. 2. Alternatively, apply the specific patch from GitHub PR #8604. 3. Restart all InLong services after patching.
🔧 Temporary Workarounds
Network Isolation
allRestrict network access to Apache InLong instances to only trusted sources
Access Control Hardening
allImplement strict authentication and authorization controls around InLong administrative interfaces
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Apache InLong instances from critical systems
- Deploy web application firewall (WAF) rules to detect and block parameter manipulation attempts
🔍 How to Verify
Check if Vulnerable:
Check Apache InLong version using the application's admin interface or by examining deployment configuration files for version information.Check Version:
Check the InLong web interface or examine the pom.xml file for version informationVerify Fix Applied:
Verify the version is 1.9.0 or later, or confirm that the specific patch from PR #8604 has been applied to the codebase.📡 Detection & Monitoring
Log Indicators:
- Unusual parameter modifications in request logs
- Multiple failed authorization attempts followed by successful sensitive parameter changes
- Administrative actions from unexpected user accounts or IP addresses
Network Indicators:
- Unusual traffic patterns to InLong administrative endpoints
- Requests containing sensitive parameter names like autoDeserialize or allowLoadLocalInfile
SIEM Query:
