![Cisco Releases Patches 3 New Critical Flaws Affecting IOS XE Software](/static/build/img/news/cisco-releases-patches-3-new-critical-flaws-affecting-ios-xe-software-small.jpg)
Networking equipment maker Cisco Systems has rolled out patches to address three critical security vulnerabilities in its IOS XE network operating system that remote attackers could potentially abuse to execute arbitrary code with administrative privileges and trigger a denial-of-service condition on vulnerable devices. The most severe of the issues is CVE-2021-34770, which Cisco calls a "Logic error" that occurs during the processing of CAPWAP packets that enable a central wireless Controller to manage a group of wireless access points.

Cisco has addressed an almost maximum severity authentication bypass Enterprise NFV Infrastructure Software vulnerability with public proof-of-concept exploit code.CVE-2021-34746 is caused by incomplete validation of user-supplied input passed to an authentication script during the sign-in process which allows unauthenticated, remote attackers to log into unpatched device as an administrator.
![Critical Flaw Discovered in Cisco APIC for Switches — Patch Released](/static/build/img/news/critical-flaw-discovered-in-cisco-apic-for-switches-patch-released-1-small.jpg)
Cisco Systems on Wednesday issued patches to address a critical security vulnerability affecting the Application Policy Infrastructure Controller interface used in its Nexus 9000 Series Switches that could be potentially abused to read or write arbitrary files on a vulnerable system. " A successful exploit could allow the attacker to read or write arbitrary files on an affected device," the company said in an advisory.
