Types ¶

type Module ¶

type Module struct {
	modkit.BaseActiveModule
	// contains filtered or unexported fields
}

Module implements the Mass Assignment active scanner.

func New ¶

func New() *Module

New creates a new Mass Assignment module.

func (*Module) CanProcess ¶

func (m *Module) CanProcess(ctx *httpmsg.HttpRequestResponse) bool

CanProcess returns true only for POST/PUT/PATCH with JSON content type.

func (*Module) IncludesBaseCanProcess ¶

func (m *Module) IncludesBaseCanProcess() bool

IncludesBaseCanProcess returns false since we have fully custom CanProcess.

func (*Module) ScanPerRequest ¶

func (m *Module) ScanPerRequest(
	ctx *httpmsg.HttpRequestResponse,
	httpClient *http.Requester,
	scanCtx *modkit.ScanContext,
) ([]*output.ResultEvent, error)

ScanPerRequest tests mass assignment on the given JSON request.

Detection is differential: a privilege key is only reported when injecting it actually changes the response AND the key appears in the response because of our injection (it is absent from the untouched baseline). A benign canary key is sent first; if the endpoint echoes that too, it reflects arbitrary input indiscriminately and we report nothing — this avoids flagging endpoints that simply ignore or blindly mirror unknown fields without honoring them.
