SSRF (Server Side Request Forgery)

Server-Side Request Forgery, or SSRF, is a type of security vulnerability that occurs when an attacker manipulates a web application to make requests on behalf of the server. SSRF exploits the trust relationship between the server and the targeted internal or external systems, enabling the attacker to bypass access controls and gain unauthorized access to sensitive information or resources.

Attackers can use SSRF to perform actions such as scanning internal networks, bypassing firewalls, or interacting with other services and APIs that the server has access to, all while masquerading as the server itself. SSRF vulnerabilities typically arise from web applications that do not properly validate or sanitize user-supplied input before using it to craft server-side requests.

To mitigate SSRF risks, developers should implement proper input validation and sanitization, utilize allowlists for acceptable target URLs, and follow the principle of least privilege when configuring server access controls. Additionally, monitoring and logging server activity can help detect and respond to potential SSRF attacks.
