A vulnerability in Cisco WebEx Meeting Center could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of an affected system. The vulnerability is due to insufficient input validation of some parameters that are passed to the web server of the affected system. An attacker could exploit this vulnerability by convincing a user to follow a malicious link or by intercepting a user request and injecting malicious code into the request. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected web interface or allow the attacker to access sensitive browser-based information.

A vulnerability in Cisco WebEx Event Center could allow an authenticated, remote attacker to view unlisted meeting information. The vulnerability is due to a design flaw in the product. An attacker could execute a query on an Event Center site to view scheduled meetings. A successful query would show both listed and unlisted meetings in the displayed information. An attacker could use this information to attend meetings that are not available for their attendance. • http://www.securityfocus.com/bid/101999 http://www.securitytracker.com/id/1039920 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171129-webex4 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

A vulnerability in Cisco WebEx Meeting Center could allow an authenticated, remote attacker to initiate connections to arbitrary hosts, aka a "URL Redirection Vulnerability." The vulnerability is due to insufficient access control for HTTP traffic directed to the Cisco WebEx Meeting Center. An attacker could exploit this vulnerability by sending a malicious URL to the Cisco WebEx Meeting Center. An exploit could allow the attacker to connect to arbitrary hosts.

CVSS: 9.3EPSS: 87%CPEs: 54EXPL: 0CVE-2017-3823 – Cisco WebEx Chrome Extension Remote Command Execution
https://notcve.org/view.php?id=CVE-2017-3823
An issue was discovered in the Cisco WebEx Extension before 1.0.7 on Google Chrome, the ActiveTouch General Plugin Container before 106 on Mozilla Firefox, the GpcContainer Class ActiveX control plugin before 10031.6.2017.0126 on Internet Explorer, and the Download Manager ActiveX control plugin before 2.1.0.10 on Internet Explorer. A vulnerability in these Cisco WebEx browser extensions could allow an unauthenticated, remote attacker to execute arbitrary code with the privileges of the affected browser on an affected system. This vulnerability affects the browser extensions for Cisco WebEx Meetings Server and Cisco WebEx Centers (Meeting Center, Event Center, Training Center, and Support Center) when they are running on Microsoft Windows. The vulnerability is a design defect in an application programing interface (API) response parser within the extension. An attacker that can convince an affected user to visit an attacker-controlled web page or follow an attacker-supplied link with an affected browser could exploit the vulnerability. • http://www.securityfocus.com/bid/95737 http://www.securitytracker.com/id/1037680 https://0patch.blogspot.com/2017/01/micropatching-remote-code-execution-in.html https://blog.filippo.io/webex-extension-vulnerability https://bugs.chromium.org/p/project-zero/issues/detail?id=1096 https://bugs.chromium.org/p/project-zero/issues/detail?id=1100 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170124-webex https://www.kb.cert.org/vuls/id/909240 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
