CVE-2000-0275

The exploit describes a vulnerability in CRYPTOCard CRYPTOAdmin where a fixed 4-byte key generation value allows retrieval of PIN numbers from .pdb files, enabling token duplication and unauthorized network access.

This exploit decrypts the PIN from a CRYPTOCard .pdb file by brute-forcing a weak DES key derived from a fixed 4-byte value. It reads the ciphertext from the file and attempts decryption with incrementally generated keys until the correct PIN is found.
