Maintainers of the PHP programming language recently released the latest versions of PHP to patch multiple high-severity vulnerabilities in its core and bundled libraries, the most severe of which could allow remote attackers to execute arbitrary code and compromise targeted servers. Hypertext Preprocessor, commonly known as PHP, is the most popular server-side web programming language that powers over 78 percent of the Internet today. The latest releases under several maintained branches include PHP version 7.3.9, 7.2.22 and 7.1.32, addressing multiple security vulnerabilities. Depending on the type, occurrence, and usage of the affected codebase in a PHP application, successful exploitation of some of the most severe vulnerabilities could allow an attacker to execute arbitrary code in the context of the affected application with associated privileges. On the other hand, failed attempts at exploitation will likely result in a denial of service (DoS) condition on the affect...

A security researcher recently reported a critical vulnerability in one of the most popular open source PHP libraries used to send emails that allowed a remote attacker to execute arbitrary code in the context of the web server and compromise a web application. Disclosed by Polish security researcher Dawid Golunski of Legal Hackers, the issue ( CVE-2016-10033 ) in PHPMailer used by more than 9 Million users worldwide was thought to be fixed with the release of version 5.2.18. However, Golunski managed to bypass the patched version of PHPMailer that was given a new CVE ( CVE-2016-10045 ), which once again put millions of websites and popular open source web apps, including WordPress, Drupal, 1CRM, SugarCRM, Yii, and Joomla, at risk of remote code execution attack. PHPMailer eventually fixed the issue with an update, version 5.2.20 . All versions of PHPMailer before this critical release are affected, so web administrators and developers are strongly recommended to update to t...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

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...

A critical vulnerability has been discovered in PHPMailer , which is one of the most popular open source PHP libraries to send emails used by more than 9 Million users worldwide. Millions of PHP websites and popular open source web applications, including WordPress, Drupal, 1CRM, SugarCRM, Yii, and Joomla comes with PHPMailer library for sending emails using a variety of methods, including SMTP to their users. Discovered by Polish security researcher Dawid Golunski of Legal Hackers , the critical vulnerability ( CVE-2016-10033 ) allows an attacker to remotely execute arbitrary code in the context of the web server and compromise the target web application. "To exploit the vulnerability an attacker could target common website components such as contact/feedback forms, registration forms, password email resets and others that send out emails with the help of a vulnerable version of the PHPMailer class," Golunski writes in the advisory published today. Golunski respo...

Cyber attacks get bigger, smarter, more damaging. P*rnHub launched its bug bounty program two months ago to encourage hackers and bug bounty hunters to find and responsibly report flaws in its services and get rewarded. Now, it turns out that the world's most popular p*rn*graphy site has paid its first bounty payout. But how much? US $20,000! Yes,  P*rnHub  has paid $20,000 bug bounty to a team of three researchers, who gained Remote Code Execution (RCE) capability on its servers using a zero-day vulnerability in PHP – the programming language that powers  P*rnHub 's website. The team of three researchers, Dario Weißer (@haxonaut), cutz and Ruslan Habalov (@evonide), discovered two use-after-free vulnerabilities ( CVE-2016-5771/CVE-2016-5773 ) in PHP's garbage collection algorithm when it interacts with other PHP objects. One of those is PHP's unserialize function on the website that handles data uploaded by users, like hot pictures, on multiple pat...

A serious zero-day vulnerability has been discovered in ImageMagick , a widely popular software tool used by a large number of websites to process user's photos, which could allow hackers to execute malicious code remotely on servers. ImageMagick is an open-source image processing library that lets users resize, scale, crop, watermarking and tweak images. The ImageMagick tool is supported by many programming languages, including Perl, C++, PHP, Python, Ruby and is being deployed by Millions of websites, blogs, social media platforms, and popular content management systems (CMS) such as WordPress and Drupal. Slack security engineer Ryan Huber disclosed a zero-day flaw (CVE-2016–3714) in the ImageMagick image processing library that allows a hacker to execute malicious code on a Web server by uploading maliciously-crafted image. For example, by uploading a booby-trapped selfie to a web service that uses ImageMagick, an attacker can execute malicious code on the website...

Security researchers from Russian Internet giant Yandex have discovered a new piece of malware that is being used to target Linux and FreeBSD web servers in order to make them a part of the wide botnet, even without the need of any root privileges. Researchers dubbed the malware as Mayhem, a nasty malware modular that includes a number of payloads to cause malicious things and targets to infect only those machines which are not updated with security patches or less likely to run security software. So far, researchers have found over 1,400 Linux and FreeBSD servers around the world that have compromised by the malware , with potentially thousands more to come. Most of the compromised machines are located in the USA, Russia, Germany and Canada. Three security experts, Andrej Kovalev, Konstantin Ostrashkevich and Evgeny Sidorov , who work at Russia-based Internet portal Yandex, discovered the malware targeting *nix servers . They were able to trace transmissions from th...
