A vulnerability in the user interface of Cisco Webex Meetings and Cisco Webex Meetings Server Software could allow an authenticated, remote attacker to inject a hyperlink into a meeting invitation email. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by entering a URL into a field in the user interface. A successful exploit could allow the attacker to generate a Webex Meetings invitation email that contains a link to a destination of their choosing. Because this email is sent from a trusted source, the recipient may be more likely to click the link.

A vulnerability in the web-based management interface of Cisco Webex Meetings could allow an unauthenticated, remote attacker to redirect a user to an untrusted web page, bypassing the warning mechanism that should prompt the user before the redirection. This vulnerability is due to improper input validation of the URL parameters in an HTTP request. An attacker could exploit this vulnerability by persuading a user to click a crafted link. A successful exploit could allow the attacker to redirect a user to a malicious website, bypassing the Webex URL check that should result in a warning before the redirection to the web page. Attackers may use this type of vulnerability, known as an open redirect attack, as part of a phishing attack to convince users to unknowingly visit malicious sites.

A vulnerability in the reclaim host role feature of Cisco Webex Meetings and Cisco Webex Meetings Server could allow an authenticated, remote attacker to take over the host role during a meeting. This vulnerability is due to a lack of protection against brute forcing of the host key. An attacker could exploit this vulnerability by sending crafted requests to a vulnerable Cisco Webex Meetings or Webex Meetings Server site. A successful exploit would require the attacker to have access to join a Webex meeting, including applicable meeting join links and passwords. A successful exploit could allow the attacker to acquire or take over the host role for a meeting.

A vulnerability in virtualization channel messaging in Cisco Webex Meetings Desktop App for Windows could allow a local attacker to execute arbitrary code on a targeted system. This vulnerability occurs when this app is deployed in a virtual desktop environment and using virtual environment optimization. This vulnerability is due to improper validation of messages processed by the Cisco Webex Meetings Desktop App. A local attacker with limited privileges could exploit this vulnerability by sending malicious messages to the affected software by using the virtualization channel interface. A successful exploit could allow the attacker to modify the underlying operating system configuration, which could allow the attacker to execute arbitrary code with the privileges of a targeted user. Note: This vulnerability can be exploited only when Cisco Webex Meetings Desktop App is in a virtual desktop environment on a hosted virtual desktop (HVD) and is configured to use the Cisco Webex Meetings virtual desktop plug-in for thin clients.

Multiple vulnerabilities in Cisco Webex Network Recording Player for Windows and Cisco Webex Player for Windows could allow an attacker to execute arbitrary code on an affected system. The vulnerabilities are due to insufficient validation of certain elements of a Webex recording that is stored in the Advanced Recording Format (ARF) or Webex Recording Format (WRF). An attacker could exploit these vulnerabilities by sending a user a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file with the affected software on the local system. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the targeted user.

A vulnerability in Cisco Webex Meetings Desktop App for Windows could allow an unauthenticated, remote attacker to overwrite arbitrary files on an end-user system. The vulnerability is due to improper validation of URL parameters that are sent from a website to the affected application. An attacker could exploit this vulnerability by persuading a user to follow a URL to a website that is designed to submit crafted input to the affected application. A successful exploit could allow the attacker to overwrite arbitrary files on the affected system, possibly corrupting or deleting critical system files.

A vulnerability in certain web pages of Cisco Webex Meetings and Cisco Webex Meetings Server could allow an unauthenticated, remote attacker to modify a web page in the context of a browser. The vulnerability is due to improper checks on parameter values within affected pages. An attacker could exploit this vulnerability by persuading a user to follow a crafted link that is designed to pass HTML code into an affected parameter. A successful exploit could allow the attacker to alter the contents of a web page to redirect the user to potentially malicious web sites, or the attacker could leverage this vulnerability to conduct further client-side attacks.
