[原文]PalmVNC 1.40 and earlier stores passwords in plaintext in the PalmVNCDB, which is backed up to PCs that the Palm is synchronized with, which could allow attackers to gain privileges.


        PalmVNC使用"backup bit"功能会把密码等敏感信息以明文方式存储在PalmVNCDB.PDB中,攻击者可以通过此文件获得VNC服务器的IP地址、主机名、用户名和口令等信息。

- 漏洞讨论

PalmVNC stores password credentials in plaintext. These credentials may be stored on a desktop system when the Palm is "Hotsynced". This could expose credentials to other users of the system that the backup is stored on.

This issue was reported in PalmVNC 1.40. Other versions are also likely affected.

- 漏洞利用

There is no exploit required.
