Hackers have exploited an unpatched zero-day vulnerability in Cisco’s networking software to compromise tens of thousands of devices, researchers have warned.

Cisco on Monday issued an advisory warning that a critical-rated vulnerability in IOS XE, the software that powers the company’s range of networking devices, was being actively exploited by hackers. Cisco said the bug was found in the IOS XE web administration interface, which can be exploited when an affected device is exposed to the internet.
