CVE-2023-33221
6.8 · MEDIUMOverview
CVE-2023-33221 is a medium-severity vulnerability affecting idemia sigma_lite_firmware. It was published on December 15, 2023 and has a CVSS 3.1 base score of 6.8 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.8, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from idemia. Update sigma_lite_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
