#1911 Cisco patches critical flaw in WebEx Chrome plugin
A vulnerability in the Cisco WebEx Chrome Plugin, used by tens of millions for web conferencing in business environments, exposed computers to remote code execution.

Cisco has patched the flaw, details of which were disclosed Monday by Google Project Zero researcher Tavis Ormandy, who has made a number of high-profile discoveries and disclosures in popular enterprise and security software.

The core issue is what Ormandy calls a “magic URL” used by the extension during WebEx sessions. The researcher said attacks could be carried out so long as a URL request contains the string cwcsf-nativemsg-iframe-43c85c0d-d633-af5e-c056-32dc7efc570b.html; attackers could use this in an iframe, leaving users unaware of an active exploit.
