CVE-2022-2067
📋 TL;DR
This CVE describes a SQL injection vulnerability in the Rosariosis educational management software prior to version 9.0. Attackers can inject malicious SQL queries through user inputs, potentially allowing unauthorized database access. All users running Rosariosis versions before 9.0 are affected.
💻 Affected Systems
- Rosariosis
📦 What is this software?
Rosariosis by Rosariosis
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, authentication bypass, and potential remote code execution through database functions.
Likely Case
Unauthorized data access, data exfiltration, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing successful exploitation.
🎯 Exploit Status
SQL injection vulnerabilities are commonly exploited, and proof-of-concept details are available in the referenced bounty report.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 9.0
Vendor Advisory: https://github.com/francoisjacquet/rosariosis/commit/15d5e8700d538935b5c411b2a1e25bcf7e16c47c
Restart Required: Yes
Instructions:
1. Backup your current installation and database. 2. Download Rosariosis version 9.0 or later from the official repository. 3. Replace the existing installation files with the new version. 4. Restart your web server. 5. Verify the application functions correctly.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests.
Input Validation Filter
allImplement custom input validation to sanitize user inputs before processing.
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries in all database interactions.
- Restrict database user permissions to minimum required privileges and implement network segmentation.
🔍 How to Verify
Check if Vulnerable:
Check your Rosariosis version by examining the application files or configuration. If version is below 9.0, you are vulnerable.Check Version:
Check the version.php file or application configuration for version information.Verify Fix Applied:
After upgrading to version 9.0 or later, verify the fix by checking that the vulnerable code patterns have been replaced with parameterized queries.📡 Detection & Monitoring
Log Indicators:
- Unusual database queries in application logs
- SQL syntax errors in error logs
- Multiple failed login attempts with SQL-like patterns
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in parameters
- Unusual database connection patterns
SIEM Query:
source="web_server_logs" AND ("SELECT" OR "UNION" OR "INSERT" OR "UPDATE" OR "DELETE") AND status=200🔗 References
