It, therefore, urged users of affected products to update their firmware.

Mr. Reuben Muoka, Director of Public Affairs at NCC, in a statement issued Wednesday, September 28, 2022, disclosed the NCC-CSIRT advisory cited the Lenovo report, first published in the second week of September, indicating that the vulnerabilities are caused by flaws in the System Management Interrupt (SMI) Set BIOS Password SMI Handler, other systems used to configure platform settings over Windows Management Instrumentation (WMI), and a buffer overflow flaw in WMI SMI Handler.

The telecoms regulatory Commission also said successful exploitation of the vulnerabilities could allow an authenticated local attacker to bypass security restrictions, gain elevated privileges and execute arbitrary code on the targeted system.

The attacker could also send a specially crafted request to the targeted user to gain sensitive information, which could result in unauthorised Information disclosure, privilege escalation and denial of service on the targeted system.

According to NCC-CSIRT, the solution to addressing the vulnerabilities is for users to update their system firmware to the newer version(s) indicated for their product model.
