Safe from httpoxy Vulnerability or How Thinking Ahead Pays Off

httpoxy-vulnerability

A dangerous easy-to-exploit vulnerability called httpoxy discovered 15 years ago, reappeared again yesterday, leaving server-side website software potentially open to attackers. This security hole impacts a large number of PHP and CGI web-apps. This means that anything that runs on PHP, Apache, Go, HHVM, Python can be vulnerable. The exploit allows man-in-the-middle attacks that could compromise web servers and potentially access sensitive data or seize control of the code. Thanks to our unique in-house developed systems and some precautions taken ahead of time by our DevOps team, SiteGround customers are unaffected by the return of the vulnerability.

Jetpack Critical Security Vulnerability

jetpack

Today a critical vulnerability was found in one of the most popular and widely used WordPress plugins - Jetpack. Fortunately, according to the plugin authors there is no evidence that this issue has been used to hack real sites. However, an update of the plugin was released - Jetpack 4.0.3.

As usual, our security team was pro-active and updated our WAF (web application firewall), adding rules to prevent the hack from being used. This means that even if your plugin is not updated to the latest version, your site will still be protected. However, we urge all Jetpack users to update the plugin to its latest version in which the vulnerability is patched.

Critical glibc Vulnerability Patched on all SiteGround Servers

gnu

Hours ago a critical vulnerability in  the GNU C Library (glibc) was announced alongside a proof of concept for the attack. This library is one of the main components in the majority of Linux distributions (if not all) including those, used for server OS'es. Without getting into too much technicalities, the exploit allows an attacker to remotely execute code by following a simple link. That's one of the most severe vulnerabilities discovered in the recent years and potentially affects pretty much any Linux server out there.

Given that all SiteGround servers run on CentOS - a Linux distribution, we took immediate measures to secure our machines. I am happy to announce that a patch has been applied on all our servers and our customers are well protected against this security threat!

Naturally since then many of you have asked us when we would introduce the certificates on our hosting platform. For all of you who have been eagerly awaiting this moment, we are happy to say that Let’s Encrypt certificates are now available at SiteGround!
