A public security challenge is testing whether two recently patched PHP vulnerabilities, known as PHP2Shell, can be exploited to retrieve a hidden key from a server running an older PHP version. The challenge involves remote code execution flaws rated 9.2/10 severity that allow unauthorized access under certain conditions. The server used in the test runs PHP 8.4.26 with default settings, and the challenge aims to see if these flaws can be practically used to access sensitive data. PHP has released fixes for these vulnerabilities in versions 8.5.12, 8.4.27, 8.3.36, and 8.2.35, but exploitability depends on specific server configurations.
