CVE-2021-1310 – Cisco Webex Meetings Open Redirect Vulnerability
https://notcve.org/view.php?id=CVE-2021-1310
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. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-open-redirect-PWvBQ2q • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVE-2021-1311 – Cisco Webex Meetings and Cisco Webex Meetings Server Host Key Brute Forcing Vulnerability
https://notcve.org/view.php?id=CVE-2021-1311
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. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-brutef-hostkey-FWRMxVF • CWE-307: Improper Restriction of Excessive Authentication Attempts •

CVE-2020-3604 – Cisco Webex Network Recording Player and Cisco Webex Player Arbitrary Code Execution Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3604
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.
