Optionally, you can add Real-Time File Protection — antivirus protection. According to its signature bases and heuristics, the AV scanner will check files when they are accessed. For more information about the product, see the presentation: Kaspersky Embedded Systems Security.
We will try to bypass this security system and achieve privileged execution of our code on the machine, which should allow us to use the connected dispenser.
According to the structure of the solutions offered in the product, our attack strategy has the following stages:. If this feature is enabled and correctly configured, it prevents attackers from using their tools. The same goes for access through a Remote Desktop. Thus, obvious ways to enter data on the machine are left.
Adding a keyboard to the whitelist is not likely to happen because it complicates maintenance service. SYS driver captures launch of executables, scripts, and library sections loads. If it is a component from outside, the use of it will not be allowed. There are built-in interpreters in the OS, such as WScript, which can be used despite the prohibition of arbitrary script execution.
For example, it can be done like this:. The code from the file will be executed in the interpreter, and you can read and write files and registry keys, start processes, etc. It is interesting, but it will not be enough to work with the dispenser. A path to run the native code is needed. PowerShell is much more flexible in this regard, and it has direct access to the system API. You can solve the problem of script execution prohibition the same way:.
Here you can use the following bypass. By default, a rule is created that allows running binaries with digital signatures trusted in the OS. This applies to all Windows components. For example, you can use a debugger signed by Microsoft to inject a shellcode into a legitimate process. Recently, an attack scenario for this component of KESS was published. It aimed to exhaust system resources by running a large number of binary instances in parallel, which do not have to pass the whitelist to be run.
This attack would overload the verification module so that system calls to start processes were not processed within the timeout period, and after that the process was allowed to start without waiting for the KESS decision.
This way, you can achieve arbitrary code execution bypassing Device Control and Applications Launch Control whitelists in local or remote access to the PC. The next step is to escalate privileges to bypass the OS access control.
The function is called at a request to the filter port; it generates a list of modules, which are loaded into the address space of the process from the query parameters. Then, the buffer is sent back to the KESS service process to scan those modules. Pay close attention to the call of the ExAllocatePoolWithTag allocator which has a slightly odd calculation of the sz parameter before it.
The logic of the function is this:. The first idea was to replace the InMemoryOrderModuleList pointer while executing the vulnerable function so that the value of sz would be taken to overflow it; and in the second run, of copying, the list would already be of a more appropriate size to fill the allocated memory.
This is possible to achieve, taking advantage of the fact that the function implements double-fetch in relation to our data. It is not possible to seize the moment appropriate for the replacement, so we can just run the cycle, change one value to another and hope for luck. It works, but it is very unstable. Another convenient way was found by chance. We have noticed that the system has not crashed into the blue screen once when it was copying data string into the buffer from the invalid pointer to the module path.
The point is that it cannot be seen in a decompiled listing of the function, but there is a handler for the exception:. This way, we control length and content of the overflow accurately and reliably. It was suggested that this function could be called by the KESS service in the event of discovery of a certain malware, that could inject its libraries into some processes.
However, when scanning a large array of different samples, no such triggers were found. However, a user without administrator rights cannot do it. We have reversed kavshell. The function is called for each process at the start of KESS, but you also need rights to stop it. The time to use the scan is when the system begins. The exploit can be put into the autorun area which is available to the current user, and then it will restart the machine. As soon as the exploit is run, the scan will work and impact our process too.
However, it will take more time to make a spray in the pool to control the order of allocations; and, as the experiments have shown, we will not be able to make it during this time window. We will do the following: The exploit launches calculators in suspended mode, and we are buying the time that the KESS kernel needs to work with these processes. To place the object that we are controlling following the overflowing buffer, we will try to create the desired kernel memory state.
We need to understand that the vulnerable buffer is being allocated in a paged pool. This is a little inconvenient for the following reasons:. To understand further details, it is highly recommended that you familiarize yourself with the Windows kernel allocator architecture. By connecting the debugger and inspecting the PoolDescriptor. ListHeads lists of paged pools, one notices that at the time of the KESS memory scan, after Windows boots, there are allocation sizes that have not yet been involved in intensive system initialization processes.
