Cisco tells Webex users to patch critical security flaws immediately


Cisco has pushed a new patch to address four critical-severity vulnerabilities plaguing its cloud-based Webex Services platform – and has also warned Wi-Fi access points users of a bug in certain versions of IOS XE that could result in a device bootloop.
