CVE-2025-44033

9.8 CRITICAL

📋 TL;DR

This SQL injection vulnerability in oa_system oasys v1.1 allows remote attackers to execute arbitrary SQL commands via the allDirector() method. Attackers can potentially read, modify, or delete database contents, and in some configurations execute arbitrary code. All deployments using the vulnerable version are affected.

💻 Affected Systems

Products:
  • oa_system oasys
Versions: v1.1
Operating Systems: All operating systems running Java
Default Config Vulnerable: ⚠️ Yes
Notes: Any deployment using the vulnerable version with database connectivity is affected regardless of configuration.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise including data exfiltration, privilege escalation, and remote code execution leading to full control of the server.

🟠

Likely Case

Database compromise allowing data theft, modification, or deletion of sensitive information stored in the oasys application.

🟢

If Mitigated

Limited impact with proper input validation, parameterized queries, and database permissions restricting the attack surface.

🌐 Internet-Facing: HIGH
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

SQL injection vulnerabilities are commonly weaponized and public proof-of-concept exists in the referenced GitHub repository.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: Unknown

Restart Required: Yes

Instructions:

1. Monitor the official oa_system repository for security updates. 2. Apply any available patches from the vendor. 3. Restart the application after patching.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Implement strict input validation and parameterized queries in the AddressMapper.java file

# Modify src/main/java/cn/gson/oasys/mappers/AddressMapper.java to use parameterized queries

Web Application Firewall (WAF)

all

Deploy a WAF with SQL injection protection rules

# Configure WAF rules to block SQL injection patterns

🧯 If You Can't Patch

  • Isolate the vulnerable system from internet access and restrict internal network access
  • Implement database-level controls including minimal privileges and query logging

🔍 How to Verify

Check if Vulnerable:

Check if the application uses oasys v1.1 and examine the AddressMapper.java file for vulnerable allDirector() method

Check Version:

Check application version in configuration files or via application interface

Verify Fix Applied:

Verify that parameterized queries are implemented in AddressMapper.java and test with SQL injection payloads

📡 Detection & Monitoring

Log Indicators:

  • Unusual database queries
  • SQL syntax errors in application logs
  • Multiple failed login attempts with SQL patterns

Network Indicators:

  • Unusual database connection patterns
  • SQL keywords in HTTP parameters

SIEM Query:

source="application.logs" AND ("SQL" OR "database error" OR "syntax error")
