CVE-2023-37924
📋 TL;DR
CVE-2023-37924 is an SQL injection vulnerability in Apache Submarine's login functionality that allows attackers to bypass authentication and gain unauthorized access. This affects all Apache Submarine deployments running versions 0.7.0 through 0.8.0. Successful exploitation could lead to complete system compromise.
💻 Affected Systems
- Apache Submarine
📦 What is this software?
Submarine by Apache
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover via authentication bypass leading to unauthorized access to sensitive data, privilege escalation, and potential lateral movement within the environment.
Likely Case
Unauthorized login and access to the Submarine workbench, potentially exposing sensitive data and allowing further exploitation of the system.
If Mitigated
No impact if proper input validation and parameterized queries are implemented, or if the system is patched to version 0.8.0+.
🎯 Exploit Status
SQL injection vulnerabilities typically have low exploitation complexity. The vulnerability allows unauthenticated attackers to bypass login.

🔍 How to Verify
Check if Vulnerable:
Check Apache Submarine version: if version is 0.7.0 or between 0.7.0 and 0.8.0, the system is vulnerable.Check Version:
Check submarine-server version in application logs or via API endpoint if availableVerify Fix Applied:
Verify version is 0.8.0 or later and test login functionality with SQL injection attempts.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Failed login attempts with SQL syntax
- Successful logins from unexpected IP addresses
Network Indicators:
- SQL injection patterns in HTTP POST requests to login endpoints
