If you're running any PHP based website on NGINX server and have PHP-FPM feature enabled for better performance, then beware of a newly disclosed vulnerability that could allow unauthorized attackers to hack your website server remotely. The vulnerability, tracked as CVE-2019-11043 , affects websites with certain configurations of PHP-FPM that is reportedly not uncommon in the wild and could be exploited easily as a proof-of-concept (PoC) exploit for the flaw has already been released publicly. PHP-FPM is an alternative PHP FastCGI implementation that offers advanced and highly-efficient processing for scripts written in PHP programming language. The main vulnerability is an "env_path_info" underflow memory corruption issue in the PHP-FPM module, and chaining it together with other issues could allow attackers to remotely execute arbitrary code on vulnerable web servers. The vulnerability was spotted by Andrew Danau, a security researcher at Wallarm while hun

Facebook has patched two high-severity vulnerabilities in its server application that could have allowed remote attackers to unauthorisedly obtain sensitive information or cause a denial of service just by uploading a maliciously constructed JPEG image file. The vulnerabilities reside in HHVM (HipHop Virtual Machine)—a high-performance, open source virtual machine developed by Facebook for executing programs written in PHP and Hack programming languages. HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance of your Hack and PHP code while maintaining the development flexibility that the PHP language provides. Since the affected HHVM server application is open-source and free, both issues may also impact other websites that use HHVM, including Wikipedia, Box and especially those which allow their users to upload images on the server. Both the vulnerabilities, as listed below, reside due to a possible memory overflow in the GD extension of HHVM wh

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica

Three critical zero-day vulnerabilities have been discovered in PHP 7 that could allow an attacker to take complete control over 80 percent of websites which run on the latest version of the popular web programming language. The critical vulnerabilities reside in the unserialized mechanism in PHP 7 – the same mechanism that was found to be vulnerable in PHP 5 as well, allowing hackers to compromise Drupal, Joomla, Magento, vBulletin and PornHub websites and other web servers in the past years by sending maliciously crafted data in client cookies. Security researchers at Check Point's exploit research team spent several months examining the unserialized mechanism in PHP 7 and discovered "three fresh and previously unknown vulnerabilities" in the mechanism. While researchers discovered flaws in the same mechanism, the vulnerabilities in PHP 7 are different from what was found in PHP 5. Tracked as CVE-2016-7479, CVE-2016-7480, and CVE-2016-7478, the zero-day flaw
