Cyber security expert Luka Šikić of WebARX: WordPress has a critical vulnerability in ‘Simple Social Buttons’, that could allow attackers to modify the installation options
WordPress (WP) has a critical vulnerability in plugin ‘Simple Social Buttons’, that could allow attackers to modify the installation options. It has been discovered by the cyber security expert Luka Šikić of WebARX. The flaw is described “as an improper application design flow, chained with a lack of permission check”. This could result in privilege escalation and unauthorized actions in WordPress installation, allowing non-admin users to alter the options. According to the company’s blog, “a function would iterate through JSON object provided in the request and update all options with option_name from object key and option_value from a key value without checking whether the current user has permission to manage options or provided option_name belongs to that plugin.” The vulnerability affects plugin versions 2.0.4 and later, but luckily there is already patch to avoid the exploit.
