An unauthenticated remote actor could exploit these vulnerabilities to take control of an affected system. Specifically, these vulnerabilities allow the actor to create a privileged account that provides complete control over the device. According to the Cisco Talos blog, Active exploitation of Cisco IOS XE Software Web Management User Interface vulnerabilities , "Organizations should look for unexplained or newly created users on devices as evidence of potentially malicious activity relating to this threat. Exploitation of this vulnerability allows an actor to gain full administrative privileges and unauthorized access into affected systems.

Researchers have found since then that the vulnerability is widely being exploited in the wild to help install implants on affected switches and routers. Cisco IOS XE is a universally deployed Internetworking Operating System IOS that enables model-driven programmability, application hosting, and configuration management, helping to automate day-to-day tasks. The vulnerability at hand is listed as:. This vulnerability allows a remote, unauthenticated attacker to create an account on an affected system with privilege level 15 access. The attacker can then use that account to gain control of the affected system. Cisco has also yet to publish a list of affected devices, but if you are using Cisco switches, routers or Wireless LAN Controllers, you should assume they are vulnerable. The implants that were found enable the attacker to communicate with the compromised device and use that ability to monitor web traffic, perform lateral movement in the network, or use them for a machine-in-the-middle attack. The Cisco Talos team discovered there were malicious activities correlated with this vulnerability as early as September 18, The web UI feature is enabled through the ip http server or ip http secure-server commands. To determine whether the HTTP Server feature is enabled for a system, log in to the system and use the show running-config include ip http server secure active command in the CLI to check for the presence of the ip http server command or the ip http secure-server command in the global configuration. Cisco strongly recommends that customers disable the HTTP Server feature on all internet-facing systems. To disable the HTTP Server feature, use the no ip http server or no ip http secure-server command in global configuration mode. While a patch is not yet available, it is advisable to protect your organization by disabling the web interface and removing all management interfaces from the internet immediately.

This directory also contains reference PCAPs based on observed in-the-wild exploitation traffic:. For reference:. If the HTTP response consists of a hexadecimal string, this is a high-confidence indicator that the device is compromised. However, as multiple sources have mentioned 2 3 , the number of implants that can be discovered using this method has gone down significantly. Investigated network traffic to a compromised device has shown that the threat actor has upgraded the implant to do an extra header check. Thus, for a lot of devices, the implant is still active, but now only responds if the correct Authorization HTTP header is set. We took another look at the initial blogpost by Cisco Talos and noticed an extra location check in the implant code:.

What You Will Learn. The schedule specifies 3 individual software releases per year at 4 month intervals. Release Name. Identifies a series of annual releases. Major Release. Indicates a series of software releases—for example, 16 for a release from a Denali, Everest, or Fuji series and 17 for a release from Amsterdam, Bengaluru,Cupertino or Dublin series. Minor Version Number. Increases by an increment of 1 for each release that introduces significant changes to the software, support for new hardware platforms, enhancements and bug fixes for existing features and functions. For example, the March release is Release This number also indicates whether a release is a standard or extended maintenance release, based on the time-based release cadence for the software.

Digital transformation is affecting businesses and organizations on a massive scale. IT and business leaders are trying use the power of digital technologies to improve business efficiency without having to replace their existing infrastructure. They are trying to automate and orchestrate network changes to reduce OpEx using standard APIs, then providing a consistent customer experience with simpler device management and faster troubleshooting and lowering the cost of keeping the network updated. Cisco IOS XE is designed to enable you to do more tasks in less time and provides consistency across Cisco switching, routing, and wireless network devices that learns from information from across the network to create a simpler, more fluid experience. This intuitive network can automate mundane day-to-day operations, which shifts IT time and money to focus on creativity and design. Cisco IOS XE continually evolves and transforms to anticipate customer needs with exponential results, creating and driving new industries and fostering innovations that have yet to be envisioned. At Cisco, security is our top priority.

What this means is that the OS and all its processes run in the same address space on the same hardware. There are some downsides to using a monolithic kernel. Since resources are shared, one process could make the entire system unresponsive.
