A vulnerability in the web framework of Cisco WebEx could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against the user of the web interface of an affected system. The vulnerability is due to insufficient input validation of certain parameters that are passed to the affected software via the HTTP GET and HTTP POST methods. An attacker who can convince a user to follow an attacker-supplied link could execute arbitrary script or HTML code in the user's browser in the context of an affected site. Cisco Bug IDs: CSCvi71274.

Security readout for executives and security teams

CVE-2018-0357 is a cross-site scripting issue in Cisco WebEx web framework handling. If an attacker persuades a user to open a crafted link, script or HTML could run in that user's browser as part of the affected WebEx site. Exposure is limited to organizations running an affected Cisco WebEx web interface. The source bundle does not identify exact product editions, hosted/on-premises scope, or affected versions beyond 'Cisco WebEx unknown.' Treat as a moderate-priority WebEx exposure check. It is not sourced as actively exploited, but user-click XSS can affect trusted collaboration workflows and should be closed through vendor guidance. Mitigation focus: Review Cisco advisory cisco-sa-20180606-webex-xss1 for affected versions and vendor fixes.; Inventory Cisco WebEx web interfaces and match them against Cisco Bug ID CSCvi71274.; Apply vendor-recommended updates or configuration guidance where applicable..
