[CNNVD]Adobe eBook Reader文件保护限制可突破漏洞(CNNVD-200210-187)

        
        Adobe eBook Reader是一款可以阅读Adobe eBooks的客户端应用程序,可使用在Microsoft Windows和Macintosh OS 9操作系统下。Adobe Content Server是一款安全的在线销售电子书籍的产品,可提供对电子书籍内容进行保护,用户可以阅读书籍,但阅读的内容限制由发布者规定。
        Adobe eBook Reader存在设计漏洞,本地攻击者可以利用这个漏洞提升部分权限,突破发布者对文件内容的一些规定。
        假如发布者提供用户可以打印和拷贝文件内容,但限制用户只能10天内打印10页,或者10天内只有拷贝文件中10页,攻击者可以通过先备份Adobe Acrobat eBook Reader文件夹中的如下内容:
         Data\Vouchers\*.*
         Data\GB.dbd
         Data\Category.etb
         Data\Library*.etb
         Data\Library*.vld
        在Adobe Acrobat eBook Reader执行完拷贝和打印之后,然后在恢复这些备份文件,拷贝或打印的限制就恢复到原来没有执行拷贝和打印完的状态,本地攻击者可以利用这个漏洞突破发布者限制。

Adobe eBook Reader is a client side application which is able to view Adobe eBooks, available for Microsoft Windows and Macintosh OS 9. eBooks are electronic books which provide some protection for content. Users may be able to view a book, but have limited publisher defined privileges to copy content.

It is possible to bypass some quota restrictions. Non-zero quotas on copying and printing content may be bypassed by repeatedly restoring certain files used to maintain state from backups.

This vulnerability has been reported in versions of eBook Reader for Microsoft Windows. It may, however, exist on other platforms.

Data\Vouchers\*.*
Data\GB.dbd
Data\Category.etb
Data\Library*.etb
Data\Library*.vld

Adobe eBook Reader Data Backup Operation Restriction Bypass
Local Access Required Other
Loss of Integrity Solution Unknown
Exploit Public

- 漏洞描述

eBook Reader contains a flaw that may allow a malicious user to bypass Digital Rights Management (DRM). DRM control of copying, printing and lending is implemented by storing the information in the file itself, which can be backed up prior to exercising rights, and restored back to its initial state. It is possible that the flaw may allow unlimited access to restricted rights resulting in a loss of integrity.
