Name of the Vulnerable Software and Affected Versions YesWiki versions prior to 4.5.4

Description YesWiki, a wiki system written in PHP, is susceptible to remote code execution. This issue arises from an arbitrary file write capability, which can be exploited to create a file with a PHP extension.
