WIZ Bug Bounty Master Class: SSRF Vulnerability on Major Gaming Company
This vulnerability is an SSRF (Server Side Request Forgery) in a major gaming company's application. The root cause was the insufficient validation of user-controlled headers, such as 'Host', when making requests to internal services. By crafting payloads that leveraged this flaw, such as '<http://10.0.0.1> <http://internal.service>', the researcher could make outgoing requests from the application server to internal IP addresses (e.g., 10.0.0.1) and bypass network-level access controls. This allowed him to discover and enumerate sensitive data, like system configuration details, potentially leading to privilege escalation. The attacker received $5,000 for reporting the vulnerability. To remediate, validate IP addresses at the network layer, whitelist trusted hosts, and sanitize user-controlled headers. Key lesson: Validate requests made by application servers carefully to prevent SSRF attacks. #BugBounty #Cybersecurity #WebSecurity #SSRF -
