CVE-2020-3573

CVE-2020-3573 describes multiple vulnerabilities in Cisco Webex Network Recording Player for Windows and Cisco Webex Player for Windows, affecting Cisco Webex Meetings and Webex Meetings Server. These flaws stem from insufficient validation of Advanced Recording Format (ARF) or Webex Recording Format (WRF) files, allowing an attacker to execute arbitrary code on a user's system. With a CVSS score of 7.8 (High), exploitation requires user interaction (UI:R) to open a malicious file, but once successful, it grants the attacker high impact on confidentiality, integrity, and availability (C:H/I:H/A:H) with local access (AV:L). Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, indicating a low level of public attention.
