Summary
Wellbia's XIGNCODE3 xhunter1.sys kernel driver, versions 10.0.10011.16384 through 2023.12.7.78, has a privilege escalation vulnerability that provides access to the IRP_MJ_WRITE command interface, allowing any user process to request PROCESS_ALL_ACCESS. The vulnerability was not fully remediated and remains in version 2023.12.7.78.
Risk Assessment
A local attacker can gain full system privileges, potentially leading to complete system compromise and malware installation.
Recommendation
Update the XIGNCODE3 driver to the latest version if a patch is available. Limit trust in applications using this driver and monitor the system for suspicious activity.
