CVE-2021-1372 – Cisco Webex Meetings Desktop App and Webex Productivity Tools for Windows Shared Memory Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-1372
A vulnerability in Cisco Webex Meetings Desktop App and Webex Productivity Tools for Windows could allow an authenticated, local attacker to gain access to sensitive information on an affected system. This vulnerability is due to the unsafe usage of shared memory by the affected software. An attacker with permissions to view system memory could exploit this vulnerability by running an application on the local system that is designed to read shared memory. A successful exploit could allow the attacker to retrieve sensitive information from the shared memory, including usernames, meeting information, or authentication tokens. Note: To exploit this vulnerability, an attacker must have valid credentials on a Microsoft Windows end-user system and must log in after another user has already authenticated with Webex on the same end-user system. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wda-pt-msh-6LWOcZ5 • CWE-202: Exposure of Sensitive Information Through Data Queries •
CVE-2021-1221 – Cisco Webex Meetings and Cisco Webex Meetings Server Software Hyperlink Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1221
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. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wbx-linkinj-WWZpVqu9 • CWE-20: Improper Input Validation CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
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-2020-3471 – Cisco Webex Meetings and Cisco Webex Meetings Server Unauthorized Audio Information Exposure Vulnerability
https://notcve.org/view.php?id=CVE-2020-3471
A vulnerability in Cisco Webex Meetings and Cisco Webex Meetings Server could allow an unauthenticated, remote attacker to maintain bidirectional audio despite being expelled from an active Webex session. The vulnerability is due to a synchronization issue between meeting and media services on 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 could allow the attacker to maintain the audio connection of a Webex session despite being expelled. Una vulnerabilidad en Cisco Webex Meetings y Cisco Webex Meetings Server, podría permitir a un atacante remoto no autenticado mantener el audio bidireccional a pesar de haber sido expulsado de una sesión Webex activa. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-info-leak-PhpzB3sG • CWE-20: Improper Input Validation CWE-662: Improper Synchronization •
