**Name of the Vulnerable Software and Affected Versions** Cisco Webex Network Recording Player for Microsoft Windows (affected versions not specified) Cisco Webex Player for Microsoft Windows (affected versions not specified) **Description** A vulnerability exists due to improper validation of Advanced Recording Format (ARF) and Webex Recording Format (WRF) files, which could allow an attacker to execute arbitrary code on an affected system. This can be exploited by sending a malicious ARF or WRF file to a user via a link or email attachment and persuading them to open it with the affected software. The issue is also described as a buffer overflow in memory, which can be exploited using a specially crafted ARF or WRF file. **Recommendations** For Cisco Webex Network Recording Player for Microsoft Windows, at the moment, there is no information about a newer version that contains a fix for this vulnerability. For Cisco Webex Player for Microsoft Windows, at the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Cisco Webex Network Recording Player versions (affected versions not specified) Cisco Webex Player versions (affected versions not specified) **Description** The issue is related to a buffer overflow in memory, allowing a remote attacker to execute arbitrary code by sending a specially crafted ARF or WRF file. The vulnerabilities exist due to improper validation of Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. An attacker could exploit these vulnerabilities by sending a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file with the affected software. **Recommendations** For Cisco Webex Network Recording Player, update to a version that properly validates ARF and WRF files to prevent arbitrary code execution. For Cisco Webex Player, update to a version that properly validates ARF and WRF files to prevent arbitrary code execution. As a temporary workaround, consider restricting the use of ARF and WRF files in the affected software until a patch is available. Avoid opening suspicious ARF or WRF files with the affected software to minimize the risk of exploitation.
