sqli-labs Less24 登录出现报错Cannot send session cache limiter....

问题描述


这是一道二次注入题,注册完成后,应该登录然后修改密码,但是登录的时候出现:

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /var/www/html/Less-24/login.php:9) in /var/www/html/Less-24/login.php on line 11

Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/Less-24/login.php:9) in /var/www/html/Less-24/login.php on line 44

Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/Less-24/login.php:9) in /var/www/html/Less-24/login.php on line 45

解决方法

这是php.ini配置里的一点问题。
找到自己的php.ini,把两个参数修改一下:

session.auto_start=0 修改为 session.auto_start=1

不太清楚这个是什么问题,据说是“UTF8文件的BOM(Byte Order Mark)标志,在保存的时候会自动存入!”

output_buffering = Off 修改为 output_buffering = On

打开所有php程序的输出缓存

修改完以后重启一下apache,就可以了
