CVSS: 5.5EPSS: 0%CPEs: 11EXPL: 0CVE-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 •

CVSS: 9.1EPSS: 0%CPEs: 7EXPL: 0CVE-2020-3419 – Cisco Webex Meetings and Cisco Webex Meetings Server Ghost Join Vulnerability
https://notcve.org/view.php?id=CVE-2020-3419
A vulnerability in Cisco Webex Meetings and Cisco Webex Meetings Server could allow an unauthenticated, remote attacker to join a Webex session without appearing on the participant list. This vulnerability is due to improper handling of authentication tokens by a vulnerable Webex site. An attacker could exploit this vulnerability by sending crafted requests to a vulnerable Cisco Webex Meetings or Cisco Webex Meetings Server site. A successful exploit requires the attacker to have access to join a Webex meeting, including applicable meeting join links and passwords. The attacker could then exploit this vulnerability to join meetings, without appearing in the participant list, while having full access to audio, video, chat, and screen sharing capabilities. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-auth-token-3vg57A5r • CWE-913: Improper Control of Dynamically-Managed Code Resources •
CVSS: 9.3EPSS: 0%CPEs: 10EXPL: 0CVE-2020-3603 – Cisco Webex Network Recording Player and Cisco Webex Player Arbitrary Code Execution Vulnerabilities
https://notcve.org/view.php?id=CVE-2020-3603
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. Múltiples vulnerabilidades en Cisco Webex Network Recording Player para Windows y Cisco Webex Player para Windows, podrían permitir a un atacante ejecutar código arbitrario en un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-nbr-NOS6FQ24 https://www.zerodayinitiative.com/advisories/ZDI-20-1361 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
