📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise including credential theft, data exfiltration, and potential remote code execution via database functions.

🟠

Likely Case

Unauthorized data access, privilege escalation, and potential system compromise through SQL injection.

🟢

If Mitigated

Limited impact with proper input validation, WAF protection, and network segmentation in place.

🌐 Internet-Facing: HIGH - The vulnerability is remotely exploitable and public exploit details exist.
🏢 Internal Only: HIGH - Even internal systems are vulnerable to authenticated or unauthenticated attacks depending on configuration.

🎯 Exploit Status

Public PoC: ⚠️ Yes

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: Not available

Restart Required: No

Instructions:

No official patch available. Consider upgrading to a newer version of Tongda OA if available, or implement workarounds.

🔧 Temporary Workarounds

WAF Rule Implementation

all

Deploy web application firewall rules to block SQL injection patterns targeting the mr_id parameter

# Example ModSecurity rule: SecRule ARGS:mr_id "@detectSQLi" "id:1001,phase:2,deny,status:403"

URL Access Restriction

linux

Block access to the vulnerable endpoint using web server configuration

# Apache: <Location "/pda/meeting/apply.php"> Require all denied </Location>
# Nginx: location ~ /pda/meeting/apply\.php { deny all; }

🧯 If You Can't Patch

  • Implement network segmentation to isolate Tongda OA systems from critical infrastructure
  • Deploy intrusion detection systems monitoring for SQL injection patterns in web traffic

🔍 How to Verify

Check if Vulnerable:

Test the /pda/meeting/apply.php endpoint with SQL injection payloads in the mr_id parameter

Check Version:

Check Tongda OA version through admin interface or version files in installation directory

Verify Fix Applied:

Verify that SQL injection attempts no longer succeed and return appropriate error responses

📡 Detection & Monitoring

Log Indicators:

  • SQL syntax errors in web server logs
  • Unusual database queries from web application user
  • Multiple failed parameter manipulation attempts

Network Indicators:

  • HTTP requests to /pda/meeting/apply.php with SQL keywords in parameters
  • Unusual outbound database connections from web server

SIEM Query:

source="web_server" AND (uri="/pda/meeting/apply.php" AND (param="mr_id" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "--"))
