Summary
The WordPress plugin All in One SEO Pack is prone to a remote code execution (RCE) vulnerability.
Insight
Insight
The All in One SEO - Best WordPress SEO Plugin enables authenticated users with 'aioseo_tools_settings' privilege (most of the time admin) to execute arbitrary code on the underlying host. Users can restore plugin's configuration by uploading a backup .ini file in the section 'Tool > Import/Export'. However, the plugin attempts to unserialize values of the .ini file. Moreover, the plugin embeds Monolog library which can be used to craft a gadget chain and thus trigger system command execution.
