Question 3

An advanced security audit of a national identification card, compliant with ISO/IEC 7816-4:2020, reveals a critical vulnerability. An unauthorized entity has demonstrated the ability to extract sensitive data, including portions of the card\'s cryptographic key material, by crafting specific APDUs. The exploit involves leveraging the Extended Length command structure, where a meticulously constructed command with an unusually large length field, followed by a minimal amount of actual data, causes the card’s internal processing unit to incorrectly parse subsequent internal memory segments as part of the legitimate data transfer. This unintended data disclosure occurs because the card’s implementation fails to rigorously validate the integrity of the data length parameter against the received data stream and the expected command boundaries.
