Description

A Download of Code Without Integrity Check vulnerability in the update modules in ASUS Member Center(华硕大厅) allows a local user to achieve privilege escalation to Administrator via exploitation of a Time-of-check Time-of-use (TOC-TOU) during the update process, where an unexpected payload is substituted for a legitimate one immediately after download, and subsequently executed with administrative privileges upon user consent. Refer to the 'Security Update for ASUS Member Center' section on the ASUS Security Advisory for more information.
