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

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

5月 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...

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...
