ibatis之sql注入
今天亲自试了一把,原来ibatis中的$是如此的危险,如果你用$的话,很可能就会被sql注入!!! 所以: 使用:select * from t_user where name like '%'||#name #||'%' 禁用:select * from t_user where name like '%'||'$name$'||'%' 解释: 预编译语句已经对o
今天亲自试了一把,原来ibatis中的$是如此的危险,如果你用$的话,很可能就会被sql注入!!!
所以:
使用:select * from t_user where name like '%'||#name #||'%'
禁用:select * from t_user where name like '%'||'$name$'||'%'
解释:
预编译语句已经对oracle的特殊字符单引号,进行了转义。即将单引号视为查询内容,,而不是字符串的分界符。
由于SQL注入其实就是借助于特殊字符单引号,生成or 1= 1这种格式的sql。预编译已经对单引号进行了处理,所以可以防止SQL注入
