Dubious security vulnerability: A program does not run correctly if you run it the wrong way, redux

Dubious security vulnerability: A program does not run correctly if you run it the wrong way, redux

This humorous yet insightful article by Raymond Chen explores a so-called “security vulnerability” in Windows where a program like XYZ.exe crashes when misconfigured to run outside its intended context—as a service launched by file association or shortcut. Through examples involving file handler changes, denial-of-service misconfigurations, and shortcut execution, the post emphasizes the difference between actual security risks and user-induced errors. For developers and security researchers, this breakdown sheds light on Windows privilege boundaries, file association behavior, and why not every crash is a vulnerability worthy of a bounty.
