CAPEC 描述
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.
CAPEC 資訊
前置條件
Signer and recipient are using complex data storage structures that allow for a mix between signed and unsigned dataRecipient is using signature verification software that does not maintain separation between signed and unsigned data once the signature has been verified.
所需技能
The attacker may need to continuously monitor a stream of signed data, waiting for an exploitable message to appear.Attacker must be able to create malformed data blobs and know how to insert them in a location that the recipient will visit.
緩解措施
Ensure the application is fully patched and does not allow the processing of unsigned data as if it is signed data.相關弱點
