Magento, the popular e-commerce platform used by more than 250,000 merchants worldwide, is affected by a potentially serious vulnerability that can be exploited to hijack online stores, researchers warned.The flaw was found by DefenseCode in November and reported to Magento via the company\u2019s Bugcrowd-based bug bounty program. The vendor indicated at the time that it had been aware of the issue, but it still hasn\u2019t addressed it. After its attempts to obtain a status update on the vulnerability failed, DefenseCode decided to make its findings public.The vulnerability is related to a feature that allows users to add Vimeo video content for an existing product. When a video is added, Magento automatically retrieves a preview image via a POST request.<\/p>\n
This request method can be changed from POST to GET, allowing an attacker to launch a cross-site request forgery (CSRF) attack and upload an arbitrary file. While invalid image files are not allowed, the file is still saved on the server before it is validated.The location of the file can be easily determined, enabling a hacker to upload a malicious PHP script to the server. In order to achieve remote code execution, the attacker also needs to upload a .htaccess<\/em> file to the same directory.<\/p>\n For the attack to work, a hacker needs to convince a user with access to the shop\u2019s administration panel, regardless of their role and permissions, to access a specially crafted web page that triggers the CSRF attack<\/p>\n http:\/\/www.securityweek.com\/unpatched-magento-flaw-exposes-online-stores-attacks<\/p>\n","protected":false},"excerpt":{"rendered":" Magento, the popular e-commerce platform used by more than 250,000 merchants worldwide, is affected by a potentially serious vulnerability that can be exploited to hijack online stores, researchers warned.The flaw was found by DefenseCode in November and reported to Magento via the company\u2019s Bugcrowd-based bug bounty program.
