The vulnerabilities primarily affect Lenovo Products (Desktop, Desktop-All in One, Hyperscale, Lenovo Notebook, Smart Office, Storage, ThinkAgile, ThinkPad, ThinkServer, ThinkStation, and ThinkSystem).
The Nigerian Communications Commission’s Computer Security Incident Response Team (NCC-CSIRT), has advised users of Lenovo products and others to update their firmware in view of admission by the firm of vulnerabilities of it’s products and it’s damage potential .
The advisory cited the Lenovo report, first published in the second week of this month, 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 regulatory body stated that 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 unauthorized Information disclosure, privilege escalation and denial of service on the targeted system.
Rueben Mouka,Director of Public Affairs of NCC quoted CSIRT as saying that the solution to addressig the vulnerabilities is for users to update their system firmware to the newer version(s) indicated for their product model.
The CSIRT it will be recalled is the telecom sector’s cyber security incidence centre set up by the NCC to focus on incidents in the telecom sector and as they may affect telecom consumers and citizens at large. The CSIRT also works collaboratively with the Nigeria Computer Emergency Response Team (ngCERT), established by the Federal Government to reduce the volume of future computer risk incidents by preparing, protecting, and securing Nigerian cyberspace to forestall attacks, and problems or related events.
