使用Snuffleupagus保护PHP

之前介绍了使用Suhosin保护PHP,由于Suhosin仅支持到php5.x,对于php7.x及以上版本可以试试Snuffleupagus

编译安装:

git clone https://github.com/jvoisin/snuffleupagus
cd snuffleupagus/src
phpize
./configure --with-php-config=/usr/local/php/bin/php-config --enable-snuffleupagus
make
make install

然后在php.ini中引用

[Snuffleupagus]
extension=snuffleupagus.so
sp.configuration_file=/usr/local/php/conf.d/snuffleupagus.rules

其中/usr/local/php/conf.d/snuffleupagus.rules为规则文件,内容可参考:

sp.eval_blacklist.list("base64_decode,system,exec,shell_exec,passthru,proc_open,proc_close, proc_get_status,checkdnsrr,getmxrr,getservbyname,getservbyport, syslog,popen,show_source,highlight_file,dl,socket_listen,socket_create,socket_bind,socket_accept, socket_connect, stream_socket_server, stream_socket_accept,stream_socket_client,ftp_connect, ftp_login,ftp_pasv,ftp_get,sys_getloadavg,disk_total_space, disk_free_space,posix_ctermid,posix_get_last_error,posix_getcwd, posix_getegid,posix_geteuid,posix_getgid, posix_getgrgid,posix_getgrnam,posix_getgroups,posix_getlogin,posix_getpgid,posix_getpgrp,posix_getpid, posix_getppid,posix_getpwnam,posix_getpwuid, posix_getrlimit, posix_getsid,posix_getuid,posix_isatty, posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid, posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname");

和Suhosin一样,可以设置函数黑白名单。

使用Suhosin保护PHP

1、下载
PHP 5.2.X:https://download.suhosin.org/suhosin-0.9.37.1.tar.gz
PHP 5.X:https://download.suhosin.org/suhosin-0.9.38.tar.gz
2、安装

wget http://download.suhosin.org/suhosin-0.9.37.1.tar.gz
tar zxvf suhosin-0.9.37.1.tar.gz
cd suhosin-0.9.37.1/
phpize
./configure  --with-php-config=/usr/local/php/bin/php-config
make
make install

编辑/usr/local/php/etc/php.ini文件,在最后一行下方插入:

[Suhosin]
extension=suhosin.so
suhosin.executor.eval.blacklist = base64_decode,system,exec,shell_exec,passthru,proc_open,proc_close, proc_get_status,checkdnsrr,getmxrr,getservbyname,getservbyport, syslog,popen,show_source,highlight_file,dl,socket_listen,socket_create,socket_bind,socket_accept, socket_connect, stream_socket_server, stream_socket_accept,stream_socket_client,ftp_connect, ftp_login,ftp_pasv,ftp_get,sys_getloadavg,disk_total_space, disk_free_space,posix_ctermid,posix_get_last_error,posix_getcwd, posix_getegid,posix_geteuid,posix_getgid, posix_getgrgid,posix_getgrnam,posix_getgroups,posix_getlogin,posix_getpgid,posix_getpgrp,posix_getpid, posix_getppid,posix_getpwnam,posix_getpwuid, posix_getrlimit, posix_getsid,posix_getuid,posix_isatty, posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid, posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname
suhosin.log.file.name = /usr/local/php/logs/suhosin-alert.log

对于php7.x及以上版本,可以试试使用Snuffleupagus保护PHP

ini_set(

今天在查看messages日志文件时,发现存在大量的错误:

Jan  4 14:41:08 myhost suhosin[954]: ALERT - script tried to disable memory_limit by setting it to a negative value -1 bytes which is not allowed (attacker '110.75.173.*', file '/home/wwwroot/2dan.cc/index.php', line 5)

后来发现原因是:index.php文件中有这么一行:

// 取消内存限制
ini_set("memory_limit",'-1');

而php.ini中

memory_limit = 128M

解决方法:

  1. 删除index.php中的

    ini_set("memory_limit",'-1');

  2. 将二处的值改为相同。
  3. 卸载 suhosin
  4. 修改php.ini

    memory_limit = -1

不推荐4,原因是可能内存会被吃光。
