CVE-2025-4023
📋 TL;DR
This critical SQL injection vulnerability in itsourcecode Placement Management System 1.0 allows attackers to execute arbitrary SQL commands via the Name parameter in /add_company.php. Attackers can potentially read, modify, or delete database contents, and the vulnerability can be exploited remotely without authentication. All organizations using this specific software version are affected.

📦 What is this software?
Placement Management System by Angeljudesuarez
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, privilege escalation to system-level access, and potential lateral movement to other systems.
Likely Case
Data exfiltration of sensitive placement/company information, database manipulation, and potential authentication bypass to gain administrative access.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation preventing database access.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily weaponizable. Remote exploitation without authentication makes this particularly dangerous.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Contact vendor for updates or implement workarounds immediately.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for all user inputs in PHP code
// Example PHP parameterized query using PDO:
$stmt = $pdo->prepare('INSERT INTO companies (name) VALUES (:name)');
$stmt->execute(['name' => $name]);
Web Application Firewall (WAF)
linuxDeploy WAF rules to block SQL injection patterns targeting /add_company.php
# Example ModSecurity rule:
SecRule ARGS:Name "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
# Example naxsi rule:
MainRule "str:--" "msg:sql comment" "mz:BODY|URL|ARGS|$HEADERS_VAR:Cookie" "s:$SQL:4" id:1000;
🧯 If You Can't Patch
- Immediately remove the system from internet-facing networks and restrict access to authorized internal users only
- Implement network segmentation to isolate the vulnerable system and limit database access
🔍 How to Verify
Check if Vulnerable:
Test the /add_company.php endpoint with SQL injection payloads in the Name parameter (e.g., ' OR '1'='1). Use automated scanners like sqlmap with caution: sqlmap -u "http://target/add_company.php" --data="Name=test"Check Version:
Check the software version in the admin panel or configuration files. Look for version indicators in source code or documentation.Verify Fix Applied:
Verify that parameterized queries are implemented and test with the same SQL injection payloads that should now be rejected or sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple failed login attempts or unusual parameter values in /add_company.php access logs
- Database logs showing unexpected queries from web application user
Network Indicators:
- HTTP requests to /add_company.php containing SQL keywords (SELECT, UNION, INSERT, etc.) in parameters
- Unusual database traffic patterns from web server IP
SIEM Query:
source="web_logs" AND uri="/add_company.php" AND (param="*SELECT*" OR param="*UNION*" OR param="*OR*1*" OR param="*--*" OR param="*;*" OR param="*'*'*'*")
