The number of vulnerabilities discovered in technical support applications installed on PCs by manufacturers keeps piling up. New exploits have been published for flaws in Lenovo Solution Center, Toshiba Service Station and Dell System Detect.The most serious flaws appear to be in Lenovo Solution Center and could allow a malicious Web page to execute code on Lenovo Windows-based computers with system privileges.The flaws were discovered by a hacker who uses the online aliases slipstream and RoL and who released a proof-of-concept exploit for them last week. This prompted the CERT Coordination Center at Carnegie Mellon University to publish a security advisory.
