CVE-2023-31098
📋 TL;DR
Apache InLong versions 1.1.0 through 1.6.0 have weak password requirements that allow users to set simple passwords. Attackers can easily guess these passwords and gain unauthorized access to user accounts. This affects all deployments using vulnerable versions of Apache InLong.
💻 Affected Systems
- Apache InLong
📦 What is this software?
Inlong by Apache
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative access to the InLong system, potentially compromising all data pipelines, stealing sensitive data, and using the system as a foothold for further attacks.
Likely Case
Attackers gain access to user accounts with standard privileges, allowing them to view, modify, or delete data pipelines and potentially escalate privileges.
If Mitigated
With strong password policies and monitoring, impact is limited to failed login attempts and alerts.
🎯 Exploit Status
Exploitation requires password guessing/brute-force attacks which are trivial to automate.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.7.0
Vendor Advisory: https://lists.apache.org/thread/1fvloc3no1gbffzrcsx9ltsg08wr2d1w
Restart Required: Yes
Instructions:
1. Backup your configuration and data. 2. Upgrade to Apache InLong 1.7.0. 3. Restart all InLong services. 4. Verify the upgrade was successful.
🔧 Temporary Workarounds
Enforce Strong Password Policy
allImplement external password policy enforcement through LDAP/AD integration or custom authentication modules.
Enable Account Lockout
allConfigure account lockout after failed login attempts to prevent brute-force attacks.
🧯 If You Can't Patch
- Implement network segmentation and restrict access to InLong instances to trusted IPs only.
- Enable detailed authentication logging and monitor for failed login attempts and password changes.
🔍 How to Verify
Check if Vulnerable:
Check InLong version via web interface or configuration files. Versions 1.1.0-1.6.0 are vulnerable.Check Version:
Check version in web UI or examine application configuration files for version information.Verify Fix Applied:
After upgrading to 1.7.0, verify that password changes now enforce complexity requirements.📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts from single IP
- Successful logins after many failures
- Password change events to simple passwords
Network Indicators:
- High volume of authentication requests to InLong endpoints
- Traffic patterns consistent with brute-force tools
SIEM Query:
