[ 'Windows 圆4', which has a vulnerable version of clfs.sys installed by default')įail_with(Failure::None, 'Session is already elevated') 'Ricardo Narvaja', # Original PoC # Original PoC # msf module For a more detailed and inĭepth analysis please refer to the following (). This is a very brief and high overview description of what the exploit is actually doing.

blf files which when being opened fill theĠx90 byte gaps created by the deallocation of the pipes in memory, creating the controlled memory space. Pipes from memory and calls CreateLogFile to open the pre-existing spray. To create thousands of read-write pipes (which take up 0x90 bytes of memory). The exploits creates a controlled memory space by first looping over the CreatePipe function to blf file is speciallyĬrafted read the SYSTEM token and write it in the process of the exploit to achieve the local privilege escalation. That points to the address of the second type of. The block of memory it reads from contains a read-write pipe blf files are specially crafted to initiate an out ofīounds read which reads from a contiguous block of memory. blf files that are edited using the technique This exploit makes use to two different kinds of specially crafted. WriteFile or fwrite respectively in order to change the contents of the file and update their checksums accordingly. However, these files can be edited with CreateFileA or with fopen and then modified with blf file and to ensure the file looks and acts like a blf file there are multiple blocks of data whichĬontain checksums to verify the integrity of the.

Open and edit '*.blf' (base log format) files. The clfs.sys driver contains a function CreateLogFile that is used to create Windows 10 21H2, Windows 11 21H2 and Windows Server 20348 operating systems. Class MetasploitModule 'Windows Common Log File System Driver (clfs.sys) Elevation of Privilege Vulnerability',Ī privilege escalation vulnerability exists in the clfs.sys driver which comes installed by default on
