Can you explain this vulnerability to me?
The vulnerability in Wellbia's XIGNCODE3 xhunter1.sys kernel driver is a privilege escalation issue. It allows any user process to access the IRP_MJ_REITS command interface, which can be used to request PROCESS_ALL_ACCESS. This means that a non-privileged user process can gain full access rights to other processes.
How can this vulnerability impact me? :
This vulnerability can allow an attacker or malicious user to escalate their privileges on the affected system. By gaining PROCESS_ALL_ACCESS, they can control or manipulate other processes, potentially leading to unauthorized actions, data theft, or system compromise.
