CVE-2023-31103

7.5 HIGH

📋 TL;DR

This vulnerability allows attackers to modify the immutable name and type of clusters in Apache InLong, potentially enabling unauthorized configuration changes. It affects Apache InLong versions 1.4.0 through 1.6.0. Organizations running these versions are at risk.

💻 Affected Systems

Products:
  • Apache InLong
Versions: 1.4.0 through 1.6.0
Operating Systems: All platforms running Apache InLong
Default Config Vulnerable: ⚠️ Yes
Notes: All deployments of affected versions are vulnerable regardless of configuration.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could reconfigure clusters to redirect data flows, intercept sensitive information, or disrupt data pipeline operations.

🟠

Likely Case

Unauthorized modification of cluster configurations leading to data integrity issues or service disruption.

🟢

If Mitigated

With proper network segmentation and access controls, impact would be limited to configuration changes within the compromised component.

🌐 Internet-Facing: HIGH if InLong management interfaces are exposed to the internet without authentication.
🏢 Internal Only: MEDIUM as attackers would need internal network access, but the vulnerability could still be exploited by malicious insiders or compromised internal systems.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

The vulnerability appears to require some level of access to the InLong management interface, but specific authentication requirements are not detailed in the advisory.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.7.0

Vendor Advisory: https://lists.apache.org/thread/bv51zhjookcnfbz8b0xsl9wv78sn0j1p

Restart Required: Yes

Instructions:

1. Backup current configuration and data. 2. Upgrade to Apache InLong 1.7.0. 3. Alternatively, apply the fix from GitHub PR #7891. 4. Restart all InLong services. 5. Verify cluster configurations remain intact.

🔧 Temporary Workarounds

Network Isolation

all

Restrict access to InLong management interfaces to trusted networks only.

Configure firewall rules to limit access to InLong ports (default 8080, 8081) to authorized IPs only

Enhanced Authentication

all

Implement additional authentication layers for cluster management operations.

Configure InLong to require strong authentication for all management API endpoints

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate InLong management interfaces
  • Enable detailed audit logging for all cluster configuration changes and monitor for unauthorized modifications

🔍 How to Verify

Check if Vulnerable:

Check the InLong version via the web interface or configuration files. Versions 1.4.0 through 1.6.0 are vulnerable.

Check Version:

Check the InLong web interface or examine the application configuration files for version information.

Verify Fix Applied:

After upgrade, verify version is 1.7.0 or later and test that cluster name/type modifications are properly restricted.

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized cluster configuration change attempts
  • Unexpected modifications to cluster names or types
  • Failed authentication attempts to management interfaces

Network Indicators:

  • Unusual traffic patterns to InLong management ports
  • Requests to cluster modification endpoints from unexpected sources

SIEM Query:

source="inlong" AND (event_type="cluster_modification" OR message="*cluster*change*")
