Namely, Linux provides the ptrace system call to observe and control another process whereas Windows provides the OpenProcess system call to obtain process handles that can then be used to interact with other API functions (e.g., ReadProcessMemory). In fact, OSs provide Application Program Interface (API) functions to support such interactions. For instance, a debugger must be able to attach itself to another process to control it and access its process memory. Whilst both processes have the same owner, interaction is not considered as a security risk as in reality many processes require such interaction to fulfill their tasks. Nonetheless, interaction is possible if two processes are owned by the same user. Hence, the OS prevents access to process memory, and does not allow interference with process execution. Process isolation acts as a core OS security function, prohibiting user interaction with processes that do not belong to them. Finally we provide recommendations on how to address the discovered vulnerability. Our study shows that this flaw can be exploited by a method to (i) disable the anti-malware suite Symantec Endpoint Protection (ii) overtake VirtualBox protected processes (iii) circumvent two major video game anti-cheat protection solutions, BattlEye and EasyAntiCheat. We show that a user-mode process can indeed obtain a fully privileged access handle before the kernel driver is notified, thus prior to the callback mechanism establishment. In this paper we are the first to demonstrate a fundamental user-mode process access control vulnerability, existing in Windows 7 up to the most recent Windows 10 OSs. Subsequently, the kernel driver performs a selective permission removal process (e.g., read access to the process memory) prior to passing a handle to the requesting process. In such cases the kernel driver establishes a callback mechanism triggered whenever a handle request for the original user-mode process is initiated by a different user process. Within the Windows family of OSs, the kernel driver is notified via dedicated routines for user-mode processes that require protection.

In scenarios of sensitive security processes (e.g., antivirus software), protection schemes are enforced at the kernel level such as to confront arbitrary user processes overtaking with malicious intent.

Modern Operating Systems (OSs) enable user processes to obtain full access control over other processes initiated by the same user.
