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.
