When I ran PHP I used it, usually as you suggest one pool per vhost, but I was only hosting my own projects and some bits for friends & family, so I didn't need to justify the setup effort against any "bottom line". You don't have a pool of processes that only specific users can take advantage of, taking up an amount of RAM (however small) each even when not actively in use. Potential customers who care much about security will most likely be looking for their own dedicated server or VM instead so there isn't really much of a market for a more secure shared host.Īlso if packing as many users as possible into as little hardware as possible, which is the only way to make any margin in shared hosting these days, you'll find mod_php more efficient by this measure. Most shared hosting environment are configured entirely out-of-the-box as the market is so saturated and margins so low there is no way to justify anything else. While we were too lazy to do a writeup, Orange Tsai published a perfect analysis in his blog.
#Hack litespeed web server code
This means that a web user may get code execution if you have vulnerable config (see below). In certain nginx + php-fpm configurations, the bug is possible to trigger from the outside. > I'm surprised FastCGI isn't more popular for that reason.įastCGI is more faf to configure where mod_php is more likely to be configured out of the box. This is an exploit for a bug in php-fpm (CVE-2019-11043). Just so we're on the same page, the most recent WP wtf involves theme developers DDOSing their competitors (who are reselling their themes) via your site.

Then I'm with you - the security record of these plugin monstrosities is truly in a league of it's own. popular PHP-based packages WordPress, Drupal, Joomla, etc. This file carries the traces of the WordPress mobile redirect hack, if it exists on your website. Perhaps you've get that impression because of the wild west shared hosting scene (made possible by CGIs and isolation in the first place) eg. The next file you need to look for is the. FCGI-like multithreaded or evented dispatch in a single process. You have to go to great lengths to achieve similar isolation if you're starting with eg. It comes with a flexible rule engine to fight against all sorts of security threats.

Both NGINX and LiteSpeed support ModSecurity, which is an open-source Web-based Firewall Application (or WAF). You need a highly secure web server to fight against all sorts of attacks and malicious software. To the contrary, CGIs, running separate per-request processes, are one of the few mainstream mechanisms to create per-request isolates transparent to the host's security infrastructure and process monitoring. You never want your site to get hacked easily. Vulnerabilities always seem to be related to CGI scripts somehow.
