Cisco has confirmed a vulnerability in a Linksys router that would allow a hacker to gain full control of the device. Security vendor DefenseCode disclosed the flaw last week, saying that it could be in multiple Linksys models. On Thursday, Cisco said the vulnerability was only in the Linksys WRT54GL. “At this point, no other Linksys products appear to be impacted,” Cisco said in a statement. Until a patch is available, Cisco recommended that customers make sure their network is securely configured.”]
