The extremely well-known Cisco’s products, including IP Phones, Routers, cameras, and switches, were determined to have several severe “zero-day” vulnerabilities by researchers in the “Cisco Discovery Protocol (CDP)”, per sources.
CDP is a proprietary “Layer 2” network protocol that is put into effect in all the Cisco devices to be privy to the mechanisms of the devices.
Reports mention that a total of five vulnerabilities were ascertained out of which, four were “Remote Code Execution” (RCE) that let hackers or any other cyber-con to manipulate every single operation of the devices without any sort of consent of the user.
According to sources, one of the vulnerabilities led to a “Denial of Service” in the Cisco FXOS, NX-OS and IOS XR software that ended up damaging the victims’ networks
By exploiting the vulnerabilities effectively, numerous organizations’ and companies’ networks were smashed, costing all the affected parties heavily.
Per legitimate sources, following is the list of all the vulnerable devices in the represented categories:
