Cisco issues fixes for numerous iOS XE, industrial router vulnerabilities

Cisco has unleashed an extensive new round of security warnings - three of them "critical" - mostly for users of its iOS XE software and industrial router family.

In total, Cisco issued 23 Security Advisories that describe 25 exposures in its IOS and IOS XE systems.
