CVE-2021-37704 PoC — Exposed phpinfo() in PhpFastCache

Source
Associated Vulnerability
Title:Exposed phpinfo() in PhpFastCache (CVE-2021-37704)
Description:PhpFastCache is a high-performance backend cache system (packagist package phpfastcache/phpfastcache). In versions before 6.1.5, 7.1.2, and 8.0.7 the `phpinfo()` can be exposed if the `/vendor` is not protected from public access. This is a rare situation today since the vendor directory is often located outside the web directory or protected via server rule (.htaccess, etc). Only the v6, v7 and v8 will be patched respectively in 8.0.7, 7.1.2, 6.1.5. Older versions such as v5, v4 are not longer supported and will **NOT** be patched. As a workaround, protect the `/vendor` directory from public access.
Description
phpinfo() is susceptible to resource exposure in unprotected composer vendor folders via phpfastcache/phpfastcache.
