Introduction Hello, I’m RyotaK ( @ryotkak ), a security engineer at Flatt Security Inc. Recently, I reported multiple vulnerabilities to several programming languages that allowed an attacker to perform command injection on Windows when the specific conditions were satisfied. Today, affected vendors published advisories of these vulnerabilities , so I’m documenting the details here to provide more information about the vulnerabilities and minimize the confusion regarding the high CVSS score. TL;DR The BatBadBut is a vulnerability that allows an attacker to perform command injection on Windows applications that indirectly depend on the CreateProcess function when the specific conditions are satisfied.
