How to investigate PHP2Shell-related activity with Sumo Logic
PHP2Shell is a pair of critical flaws in the PHP interpreter itself, each with a CVSS v4.0 score of 9.2. Both let an unauthenticated attacker run code on a web server with a single crafted web request, or a pair of them, before any application code runs. Because the bug lives in PHP, not in WordPress, Drupal or Magento, every reachable PHP endpoint on an affected server is exposed, including login pages, static forms, and health checks. Every PHP release from the last decade is affected (back to 5.4).
