How Active Directory ACL abuse works: GenericAll, GenericWrite, WriteDACL and WriteOwner, how to find the path in BloodHound and how to validate it.
Windows PG box. Remote Mouse 3.008 on port 1978 runs commands unauthenticated, FileZilla's recentservers.xml leaks divine's password, and its GUI gives SYSTEM.
CVE-2023-32315 creates an Openfire admin, a malicious plugin gives a shell, and the SMTP password stored in openfire.script turns out to be root's password.
