Cisco is warning that three recently patched critical remote code execution vulnerabilities in Cisco Identity Services Engine (ISE) are now being actively exploited in attacks.

Cisco Systems confirmed Monday it's investigating the apparent theft of source code from its network, but won't say how much may have been taken or what the consequences could be for customers.

Cisco has released security updates for a high-severity Webex vulnerability that allows unauthenticated attackers to gain client-side remote code execution using malicious meeting invite links.
