ASUS Live Update Embedded Malicious Code Vulnerability
ASUS · Live Update
The ASUS Live Update client shipped with certain versions containing unauthorized code modifications introduced through a supply chain compromise, which could cause targeted devices to perform unintended actions. An attacker did not need to act directly against a device: exposure required that a device both met specific targeting conditions and had installed one of the compromised builds.
"UNSUPPORTED WHEN ASSIGNED" Certain versions of the ASUS Live Update client were distributed with unauthorized modifications introduced through a supply chain compromise. The modified builds could cause devices meeting specific targeting conditions to perform unintended actions. Only devices that met these conditions and installed the compromised versions were affected. The Live Update client has already reached End-of-Support (EOS) in October 2021, and no currently supported devices or products are affected by this issue.
