Critical Root RCE Bug Affects Multiple Netgear SOHO Router Models

Critical Root RCE Bug Affects Multiple Netgear SOHO Router Models

November 18, 2021Ravie Lakshmanan
Networking equipment company Netgear has  released  yet  another round  of  patches  to remediate a high-severity remote code execution vulnerability affecting multiple routers that could be exploited by remote attackers to take control of an affected system. Tracked as  CVE-2021-34991  (CVSS score: 8.8), the pre-authentication buffer overflow flaw in small office and home office (SOHO) routers can lead to code execution with the highest privileges by taking advantage of an issue residing in the Universal Plug and Play ( UPnP ) feature that allows devices to discover each other's presence on the same local network and open ports needed to connect to the public Internet. Because of its ubiquitous nature, UPnP is used by a wide variety of devices, including personal computers, networking equipment, video game consoles and internet of things (IoT) devices. Specifically, the vulnerability stems from the fact that the UPnP daemon accepts unauthenticated HTTP SUBSCRIBE and UNSUBSCRI
Security Flaws in UPnP protocol put 50 million devices at risk

Security Flaws in UPnP protocol put 50 million devices at risk

A Security Flaw in Universal Plug & Play (UPnP) are exposing more than 50 millions of computers, printers and storage drives to attack by hackers remotely. Rapid7 said Tuesday in a research paper , that problem lies in routers and other networking equipment that use a commonly employed standard known as Universal Plug and Play or UPnP. UPnP allows networked devices to discover each other and automatically establish working configurations that enable data sharing, media streaming, media playback control and other services. In one common scenario a file-sharing application running on a computer can tell a router via UPnP to open a specific port and map it to the computer's local network address in order to open its file-sharing service to Internet users. Over 80 million unique IPs were identified that responded to UPnP discovery requests from the internet and around 40-50 million network-enabled devices are at risk due to vulnerabilities found in the Universa
