漏洞分析
weaver E-Office v9.5 命令执行漏洞
官网：
https://www.e-office.cn/版本：v9.5
漏洞利用函数出现在 /webroot/inc/utility_all.php 的第 1007-1008 行。自定义函数doc2txt()调用了exec()函数，$path变量不受用户控制，可以使用命令连接符号“&&”注入任意命令。
漏洞触发点位于/webroot/general/file_folder/global_search.php文件中。我们在第108行调用doc2txt()，然后追溯doc2txt()参数$FILE_PATH的来源，将附件目录(C: eoffice9webrootattachment) 以获取完整的文件路径。
注意在php配置文件（php.ini）中启用了注册全局变量设置（register_globals = On），所以第93行变量$ATTACHMENT_DATA和第106行变量$SEARCH_DOC的值需要用户在GET/POST .而103行会检查文件是否存在，所以不应该包含在命令执行中的文件中不能使用/| < > : * "? 特殊符号。
附件所在文件夹：
