Multiple Vulnerabilities in Cisco Webex Network Recording Player
Description: Multiple vulnerabilities in the Cisco Webex
Network Recording Player and Cisco Webex Player could allow an
unauthenticated, remote attacker to execute arbitrary code on the
system of a targeted user. An attacker could exploit these
vulnerabilities by sending a user a link or email attachment
containing a malicious ARF (Advanced Recording Format) or WRF
(Webex Recording Format) file via a link or an email attachment
and persuading the user to open the file with the affected
Impact: Successful exploitation of these vulnerabilities could allow the attacker to execute arbitrary code on the user’s system. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
