A vulnerability in the Webex Network Recording Admin page of Cisco Webex Meetings could allow an authenticated, remote attacker to elevate privileges in the context of the affected page. To exploit this vulnerability, the attacker must be logged in as a low-level administrator. The vulnerability is due to insufficient access control validation. An attacker could exploit this vulnerability by submitting a crafted URL request to gain privileged access in the context of the affected page. A successful exploit could allow the attacker to elevate privileges in the Webex Recording Admin page, which could allow them to view or delete recordings that they would not normally be able to access. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191106-wbs-privilege • CWE-264: Permissions, Privileges, and Access Controls •

A vulnerability in the update service of Cisco Webex Meetings Desktop App and Cisco Webex Productivity Tools for Windows could allow an authenticated, local attacker to execute arbitrary commands as a privileged user. The vulnerability is due to insufficient validation of user-supplied parameters. An attacker could exploit this vulnerability by invoking the update service command with a crafted argument. An exploit could allow the attacker to run arbitrary commands with SYSTEM user privileges. While the CVSS Attack Vector metric denotes the requirement for an attacker to have local access, administrators should be aware that in Active Directory deployments, the vulnerability could be exploited remotely by leveraging the operating system remote management tools. • https://www.exploit-db.com/exploits/46479 http://www.securityfocus.com/bid/107184 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190227-wmda-cmdinj • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

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: CSCvi63757. Una vulnerabilidad en el framework web de Cisco WebEx podría permitir que un atacante remoto sin autenticar lleve a cabo un ataque de Cross-Site Scripting (XSS) contra un usuario de dicha interfaz en el sistema afectado. • http://www.securityfocus.com/bid/104421 http://www.securitytracker.com/id/1041062 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180606-webex-xss • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
