🚨 A crafty command injection vulnerability lurks in iTextPDF versions 7.1.17 and earlier! A rogue filename could unleash chaos right from the Ghostscript command line. 🔥 Think of this as a chef who takes any order without checking the recipe. If a customer slips in a forbidden ingredient, that dish could explode in the kitchen! An attacker could manipulate the CompareTool filename to execute arbitrary commands on the server, potentially leading to full server compromise. Imagine unauthorized access to sensitive files, or worse—complete control over the server's operations! This could be absolutely devastating for any organization relying on this software.
