The Nigerian Communications Commission (NCC) yesterday warned the public as original equipment manufacturer (OEM), Lenovo, said it had discovered vendor vulnerabilities in some of its products, which it said could lead to information disclosure, privilege escalation, and denial of service.
These affect Lenovo products (Desktop, Desktop-All in One, Hyperscale, Lenovo Notebook, Smart Office, Storage, ThinkAgile, ThinkPad, ThinkServer, ThinkStation, and ThinkSystem).
NCC’s Computer Security Incident Response Team (NCC-CSIRT), in its advisory, rated the probability of the vulnerability as high with an equally high damage potential. It, therefore, urged users of affected products to update their firmware.
The advisory cited the Lenovo report, 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.
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.
