A new vulnerability has been discovered in Lenovo’s much-maligned Lenovo Solution Center (LSC) software. The vulnerability allows attackers with local network access to a PC to execute arbitrary code, said researchers at Trustwave SpiderLabs.
The flaw allows an attacker to elevate privileges and is tied to the LSC application’s backend. It opens the door for a malicious attacker to start the LSC service and trick it in to executing arbitrary code in the local system context, said Karl Sigler, a SpiderLabs researcher at Trustwave.
LSC comes preloaded on nearly all Lenovo business and consumer desktops and laptop PCs. The software acts as a dashboard monitoring system health and security – from battery life, driver updates and firewall status. Lenovo has issued a fix for the security flaw last week. This is the second time the computer maker has had to patch LSC – the first being December 2015.
“In keeping with industry best practices, Lenovo moved rapidly to ready a fix and on April 26 it updated its security advisory disclosing this additional vulnerability and the availability of a fix that addressed it,” a Lenovo spokesperson told Threatpost.
