Vulnerabilities in Cisco Webex Network Recording 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. 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. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address the vulnerabilities.”]
