Cisco tells Webex users to patch critical security flaws immediately

• Cisco patches four critical flaws in Webex Services, including SSO and Identity Services Engine RCE bugs
• No exploitation reported before fixes; users must update SAML certificates in Control Hub
• Separate IOS XE bug causes Wi‑Fi access points to bloat logs and fail updates, affecting 230+ models

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.

Webex Services is a platform for communication and collaboration, letting people hold video meetings, send messages, make calls, and share files, all from one place.
