0-Day Flaws in Vanilla Forums Let Remote Attackers Hack Websites

0-Day Flaws in Vanilla Forums Let Remote Attackers Hack Websites

May 12, 2017
A security researcher has publicly disclosed two critical zero-day vulnerabilities in Vanilla Forums, an open source software that powers discussion on over 500,000 websites, which could allow unauthenticated, remote attackers to fully compromise targeted websites easily. Discovered by Polish security researcher Dawid Golunski of Legal Hackers, two separate unpatched vulnerabilities, a remote code execution ( CVE-2016-10033 ) and host header injection ( CVE-2016-10073 ), affect the latest version of Vanilla Forums 2.3, leaving hundreds of thousands of websites and their visitors vulnerable to various hacking attacks. Vanilla Forums: Remote Code Execution Flaw According to Golunski, both vulnerabilities technically exist because Vanilla Forum is still using a vulnerable version of PHPMailer , one of the most popular open source PHP libraries used to send emails. Last year Golunski reported a critical remote code execution flaw ( CVE-2016-10033 ) in PHPMailer library that al...

Critical Updates — RCE Flaws Found in SwiftMailer, PhpMailer and ZendMail

Jan 03, 2017
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...

Between Buzz and Reality: The CTEM Conversation We All Need

Between Buzz and Reality: The CTEM Conversation We All Need

Jun 24, 2025Threat Exposure Management
I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...
