Bu saldırı kalıbı nedir?

An attacker exploits the underlying complexity of a data structure that allows for both signed and unsigned content, to cause unsigned data to be processed as though it were signed data.

Gereksinimler

Saldırının gerçekleşmesi için ne gerekir?

Ön koşullar

  • Signer and recipient are using complex data storage structures that allow for a mix between signed and unsigned data
  • Recipient is using signature verification software that does not maintain separation between signed and unsigned data once the signature has been verified.

Gerekli beceri

  • High: The attacker may need to continuously monitor a stream of signed data, waiting for an exploitable message to appear.
  • High: Attacker must be able to create malformed data blobs and know how to insert them in a location that the recipient will visit.
