And in August, a critical remote authentication-bypass vulnerability – with the highest possible severity level of 10 out of 10 on the CvSS scale – was found in the Cisco REST API virtual service container for Cisco IOS XE Software. Last July, Cisco patched a high-severity vulnerability in IOS XE, which could enable a remote attacker to reconfigure or execute commands on impacted devices. The networking giant in January also released fixes for another high-severity glitch in the web user interface of Cisco IOS and Cisco IOS XE Software. In March, Cisco issued 24 patches tied to vulnerabilities in its IOS XE operating system.

Julien Legras and Thomas Etrillard of Synacktiv were credited for reporting the flaw.Ĭisco’s IOS XE software has had its fair share of security issues. Fixed releases for Cisco IOS XE SD-WAN are below. The flaw (CVE-2019-16011) has a CVSS 3.0 score of 7.8 out of 10, which makes it high severity. “A successful exploit could allow the attacker to execute commands with root privileges.” “The attacker must be authenticated to access the CLI utility,” according to Cisco. An attacker could exploit this vulnerability by authenticating to the device and submitting a crafted input to the CLI utility, according to Cisco. The CLI does not sufficiently validate input commands. The flaw exists in the command line interface (CLI) utility of Cisco IOX XE, used to configure the network device. “The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability,” according to Cisco’s Wednesday advisory. These are all used by small businesses and enterprises alike. Affected routers include the Aggregation Services Routers (ASR) 1000 models, Integrated Services Routers (ISR) 1000 models, ISR 4000 models and Cloud Services Router 1000V models. This Linux-based version of Cisco’s Internetworking Operating System (IOS) is used in Cisco software-defined wide area network (SD-WAN) routers. Retrieved 3 August 2017.Cisco has patched a high-severity vulnerability in its router software, which if exploited could enable a local, authenticated attacker to execute arbitrary commands with root privileges. ^ "Cisco IOS XE Open Service Containers" (PDF).

Since IOS XE has IOSd running as an application on top of Linux, it becomes possible to also run different applications on the hardware, a good example of this is running Wireshark on a switch.

While IOS XE (IOSd) and IOS share a lot of the same code, IOS XR is a completely different code base. On the other hand, IOS XR is based on QNX (since version 5.0 it's also based on linux) where the IOSd application has been separated into many different applications. Differences between IOS and IOS XE Ĭisco IOS is a monolithic operating system running directly on the hardware while IOS XE is a combination of a Linux kernel and a monolithic application (IOSd) that runs on top of this kernel. IOS XE is released separately for ASR 1000 and Catalyst 3850.
