Blind Sql Injection in https://████

**Bug Bounty Report** ### Summary A SQL injection vulnerability was discovered in the User-Agent parameter of the website `https://██████████/`. This vulnerability allows an attacker to inject SQL commands through the User-Agent HTTP header, potentially leading to unauthorized access to sensitive data stored in the backend database. ████ ## Impact - Successful exploitation of this vulnerability allows an attacker to execute arbitrary SQL commands on the backend database management system (MySQL >= 8.0.0, MariaDB fork). - Potential impact includes unauthorized access to sensitive data, manipulation of database content, and even complete compromise of the database server ## System Host(s) ███ ## Affected Product(s) and Version(s) ## CVE Numbers ## Steps to Reproduce 1. **SQLMap Command**: ``` sqlmap --url "https://█████████/" --batch --random-agent --level 5 --risk 3 ``` 2. **Injection Point Identified**: ``` Parameter: User-Agent (User-Agent) Type: boolean-based blind Title: OR boolean-based blind - WHERE or HAVING clause Payload: -5127 OR 2687=2687 ``` ## Suggested Mitigation/Remediation Actions ### Recommendations - **Immediate Mitigation**: - Implement input validation and parameterized queries to sanitize user inputs, especially HTTP headers like User-Agent. - Apply web application firewall (WAF) rules to detect and block SQL injection attempts. - **Long-term Solutions**: - Regular security assessments and penetration testing to identify and remediate vulnerabilities. - Educate developers about secure coding practices, including input validation and output encoding.
