Server-Side Request Forgery
SSRF flaws occur whenever a web application fetches a remote resource without validating the user-supplied URL.
Überblick
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.
Wie Angreifer dies ausnutzen
Das Verstehen von Angriffsmustern hilft Ihnen, bessere Verteidigungen aufzubauen. Dies sind die Techniken, die Sicherheitsteams überwachen.
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.
Wie Sie vorbeugen
- 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
