CVSS 3.1
9.8 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2023-33221
Critical (9.8) in idemia. EPSS 1.0% chance of exploitation in the next 30 days.
When reading DesFire keys, the function that reads the card isn't properly checking the boundaries when copying
internally the data received. This allows a heap based buffer overflow that could lead to a potential Remote Code
Execution on the targeted device. This is especially problematic if you use Default DESFire key.
