Vulnerability from variot - Updated: 2023-12-18 13:03

Race condition in Lenovo System Update (formerly ThinkVantage System Update) before 5.06.0034 uses world-writable permissions for the update files directory, which allows local users to gain privileges by writing to an update file after the signature is validated. Lenovo System Update is prone to a local privilege-escalation vulnerability. A local attacker can exploit this vulnerability to gain elevated privileges. Lenovo System Update 5.6.0.27 and prior versions are vulnerable. Lenovo System Update (formerly known as ThinkVantage System Update) is a set of system automatic update tools provided by China Lenovo (Lenovo), which includes device driver updates, Windows system patch updates, etc
