CVE-2024-30085 is a heap-based buffer overflow vulnerability affecting the Windows Cloud Files Mini Filter Driver cldflt.sys. By crafting a custom reparse point, it is possible to trigger the buffer overflow to corrupt an adjacent _WNF_STATE_DATA object. The corrupted _WNF_STATE_DATA object can be used to leak a kernel pointer from an ALPC handle table object. A second buffer overflow is then used to corrupt another _WNF_STATE_DATA object, which is then used to corrupt an adjacent PipeAttribute object. By forging a PipeAttribute object in userspace, we are able to leak the token address and override privileges to escalate privileges to NT AUTHORITY\SYSTEM.
