VestaCP Installer Compromised

October 21, 2018

VestaCP Free Hosting control panel compromised again. Hackers where able to get access to VestaCP infrastcuture server, allowing them to modify installation script, so it sent root password of servers to hacker.

Here is post from VestaCP on their forum

I’m sorry about inactivity in this post from our side. It was a complex issue and we were not sure we understand the whole picture. Leak in the installer is just one piece of the puzzle. All pieces together lead to cumulative effect.

The issue number one

Our infrastructure server was hacked. Presumably using API bug in the release 0.9.8-20. The hackers then changed all installation scripts to log admin password and ip as addition to the distro name we used to collect stats.

Please check if your server IP here

http://vestacp.com/test/?ip=127.0.0.1

If it’s there you should change admin passwords as soon as possible. Also please make sure there is no /usr/bin/dhcprenew binary installed on your server. This binary is some sort of trojan that is able to launch remote DDoS attack or open shell to your server

October 4, 2018

by ServerOk with No Comment Uncategorized

To change PHP version for a site, first find available PHP handlers, this can be done with command

/usr/local/psa/admin/bin/php_handlers_control --list

1	/usr/local/psa/admin/bin/php_handlers_control --list

You need to find the id for the PHP handler. For PHP 5.6 fpm, it is “plesk-php56-fpm”.

To change a sites PHP version to PHP 5.6, run

plesk bin domain -u DOMAIN_NAME_HERE -php_handler_id plesk-php56-fpm

1	plesk bin domain -u DOMAIN_NAME_HERE -php_handler_id plesk-php56-fpm

When installing ffmpeg, i get error

This is due to incompatability with ffmpeg and x264.

What you can do is try another version of x264. You will be able to download older version of x264 from

ftp://ftp.videolan.org/pub/x264/snapshots

On 2018-08-14, it failed with latest stable snapshot. So i tried 14 days old stable snapshot

cd /usr/local/src/
wget ftp://ftp.videolan.org/pub/x264/snapshots/x264-snapshot-20180730-2245-stable.tar.bz2
tar xvf x264-snapshot-20180730-2245-stable.tar.bz2
cd /usr/local/src/x264-snapshot-20180730-2245-stable
make clean && make distclean
./configure --prefix=/usr --enable-shared
make && make install
ldconfig

cd /usr/local/src/

wget ftp://ftp.videolan.org/pub/x264/snapshots/x264-snapshot-20180730-2245-stable.tar.bz2

tar xvf x264-snapshot-20180730-2245-stable.tar.bz2

cd /usr/local/src/x264-snapshot-20180730-2245-stable

make clean && make distclean

./configure --prefix=/usr --enable-shared

make && make install

ldconfig

This worked with ffmpeg.

Solution here is to try latet version first, if it did not work, try older version, say try 1 month old version, if that did not work, go back 2 months, see if that works.

Now install ffmpeg with

cd /usr/local/src/
wget https://github.com/FFmpeg/FFmpeg/archive/n3.3.5.tar.gz
tar zxf n3.3.5.tar.gz
cd /usr/local/src/FFmpeg-n3.3.5/
ldconfig
make clean && make distclean
./configure --prefix=/usr --enable-shared --enable-libxvid --enable-libvorbis --enable-libtheora --enable-libmp3lame --enable-gpl --enable-libfdk-aac --enable-nonfree --enable-libx264 --enable-libfreetype
make && make install && ldconfig

cd /usr/local/src/

wget https://github.com/FFmpeg/FFmpeg/archive/n3.3.5.tar.gz

tar zxf n3.3.5.tar.gz

cd /usr/local/src/FFmpeg-n3.3.5/

ldconfig

make clean && make distclean

./configure --prefix=/usr --enable-shared --enable-libxvid --enable-libvorbis --enable-libtheora --enable-libmp3lame --enable-gpl --enable-libfdk-aac --enable-nonfree --enable-libx264 --enable-libfreetype

make && make install && ldconfig

To enable Zend OPCache in PHP, edit php.ini add following to end of the file

opcache.memory_consumption=128
opcache.max_accelerated_files=10000
opcache.validate_timestamps=1
opcache.revalidate_freq=10

opcache.enable=1

opcache.enable_cli=1

opcache.memory_consumption=128

opcache.max_accelerated_files=10000

opcache.validate_timestamps=1

opcache.revalidate_freq=10

Verify it with

[root@vps154294 php]# php -m | grep  Zend
Zend OPcache
