Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Validates inputs used in dynamic code generation to block injected directives.
Penetration testing attempts server-side requests to internal resources, identifying SSRF weaknesses for remediation.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Outbound connections to external resources can be monitored and limited at the boundary, reducing SSRF impact.
Directly prevents execution of attacker-supplied code written into data memory regions.
Detects server-side request forgery through monitoring of unexpected outbound connections.
