[原文]Directory traversal vulnerability in zml.cgi allows remote attackers to read arbitrary files via a .. (dot dot) in the file parameter.


[CNNVD]Abe Timmerman zml.cgi目录遍历漏洞(CNNVD-200112-208)

        
        zml.cgi是一个为html页面增加交互能力的脚本。
        zml.cgi程序存在典型的输入验证漏洞,可以使远程攻击者得到遍历主机上的目录,读取任意文件。
        程序未对用户输入作充份过滤,攻击者可以在file变量的赋值中混入"../"字串遍历主机上的目录,读取任意有权限读取的文件。

source: http://www.securityfocus.com/bid/3759/info

zml.cgi is a perl script which can be used to support server side include directives under Apache. It recognizes a simple set of commands, and allows access to cgi parameters and environment variables. It can run on Linux and Unix systems or any other platform with Apache and Perl support.

zml.cgi accepts as a parameter the file to parse for these ssi directives. This parameter is susceptible to the standard ../ directory traversal attack, allowing arbitrary files to be specified. Although the script attempts to append a .zml extension to any file accessed, appending a null byte to the file name parameter is sufficient to evade this restriction.

The author of the script has reported that this vulnerability does not exist in any published version of ZML, and that the file parameter has never been used by ZML. It is possible that this vulnerability exists in a modified version of ZML published by an unknown third party. If more details become available, this vulnerability will be updated.

- 漏洞描述

zml.cgi contains a flaw that allows a remote attacker to view arbitrary files outside of the web path. The issue is due to the script not properly sanitizing user input, specifically traversal style attacks (../../) supplied via the "file" variable.
