Bug Bounty Exploits: Path Traversal and SQL Injection Techniques

Security researchers have detailed real-world exploitation techniques used to identify and leverage vulnerabilities in web applications, focusing on bug bounty scenarios. One researcher described successfully exploiting a path traversal vulnerability in a company's file upload functionality, allowing arbitrary file overwrites and folder creation by manipulating file save locations. Additional attempts were made to exploit content-type handling and CSV injection, though system command execution was not achieved in that case.

Another researcher demonstrated the use of UNION-based SQL injection to enumerate database tables, extract credential columns, and ultimately dump usernames and passwords from a non-Oracle database. By exploiting a vulnerable product category filter, the attacker was able to gain administrator access, highlighting the risk of improperly sanitized user input in web applications. Both cases underscore the importance of secure coding practices and thorough application testing to prevent such vulnerabilities from being exploited in the wild.
