public function runCommand($user_input) { $result = ""; assert("$result = $user_input"); return $result; } The runCommand() method takes user-controlled input from the cmd POST parameter. The assert() function evaluates the string as PHP code. Since no sanitization is applied, an attacker can break out of the string concatenation by injecting '.phpinfo().' , leading to arbitrary code execution.
Good luck—and may your code traces be clear and your exploits be idempotent. [Your Name] is a application security engineer and holder of the OSWE certification. They failed their first OSWE attempt due to a poor report and passed the second with a 100% reproducible document. oswe exam report
Introduction: Why the Report is 50% of the Battle The Offensive Security Web Expert (OSWE) certification is one of the most respected and challenging credentials in the application security industry. Unlike multiple-choice exams or simple capture-the-flag (CTF) events, the OSWE exam is a grueling 48-hour practical test followed by a 24-hour reporting window .
