When a user opens a Cisco warranty CD with a web browser, the browser automatically accesses a currently inactive malware website without warning, Cisco said in an advisory on Wednesday.
"If this third-party website would become active as a malware repository again, there is a potential that users could infect their operating system by opening the CD with their web browser," said Cisco. In addition, if a user's system is configured to automatically open inserted media, then the CD will automatically connect the computer to the malware website when the user inserts the warranty CD, without any other interaction.
Cisco warranty CDs shipped between December 2010 and August 3, 2011 try to connect to the malware website, Cisco said.
