Cisco Webex Network Recording Player Arbitrary Code Execution Vulnerabilities

Vulnerability

The vulnerability exists in the Cisco Webex Network Recording Player for Microsoft Windows and the Cisco Webex Player for Microsoft Windows because the software improperly validates Advanced Recording Format (ARF) and Webex Recording Format (WRF) files [1]. An attacker can exploit this by sending a user a malicious ARF or WRF file via a link or email attachment [1]. The description does not specify exact affected versions but indicates the software is for Microsoft Windows [1].

Exploitation

An attacker must craft a malicious ARF or WRF file and deliver it to a user, typically via a link or email attachment [1]. The attacker then needs to persuade the user to open the file with the affected Cisco Webex Player software [1]. No additional authentication or network position is required beyond the user's action [1].

Impact

Successful exploitation allows an attacker to execute arbitrary code on the affected system [1]. This can lead to full compromise of the victim's machine, including data theft, installation of malware, or further lateral movement within the network [1].

Mitigation

Cisco has released free software updates that address the vulnerability as described in their security advisory [1]. Users should upgrade to the fixed version provided by Cisco [1]. Workarounds are not mentioned; the recommended action is to apply the patch [1].
