Server-Side Request Forgery
SSRF flaws occur whenever a web application fetches a remote resource without validating the user-supplied URL.
Resumen
New for 2021. This category represents the scenario where the security community is telling us this is important, even though it's not illustrated in the data at this time.
Cómo los Atacantes Explotan Esto
Entender los patrones de ataque te ayuda a construir mejores defensas. Estas son las técnicas que los equipos de seguridad vigilan.
Internal service access
Attackers use the server to make requests to internal services that are not directly accessible from the internet.
Cloud metadata exploitation
In cloud environments, SSRF can access instance metadata services to obtain credentials or sensitive configuration.
Cómo Prevenir
- Segment remote resource access functionality in separate networks
- Enforce URL schema, port, and destination with a positive allowlist
- Do not send raw responses to clients
- Disable HTTP redirections
- Be aware of URL consistency to avoid DNS rebinding attacks
