Memory Vulnerabilities in OpenSC Packages: Exploiting Card Enrollment Process for Unauthorized Access

CVE-2023-40661 · MEDIUM Severity

CVSS:3.1/AV:P/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H

Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB device or smart card to manipulate responses to APDUs. This manipulation can potentially allow compromise key generation, certificate loading, and other card management operations during enrollment.
