### 重置数据库账号密码防御

该文件的代码为：

<% Connection conn = null; PreparedStatement pstmt = null; String sql = "create user byoa IDENTIFIED by 'byoa'"; try { conn = null;//net.btdz.oa.common.ConnectionPoolBean.getConnection(); pstmt = conn.prepareStatement(sql); out.print(pstmt.executeUpdate()); sql = "grant all on *.* to byoa"; pstmt = conn.prepareStatement(sql); out.println(pstmt.executeUpdate()); pstmt.close(); sql = "update mysql.user set password=password('byoa') where user='byoa'"; pstmt = conn.prepareStatement(sql); out.println(pstmt.executeUpdate()); pstmt.close(); sql = "flush privileges"; pstmt = conn.prepareStatement(sql); out.print(pstmt.executeUpdate()); pstmt.close(); //conn.close(); } catch (Exception ex) { out.println(ex.getMessage()); }%>

可以抛光该文件没有验证任何权限，便进行了重置数据库用户byoa的密码为：byoa
