Regarded as the future of events, WebEx breaks in full fury as online conferences start to run their full course. However, with more businesses joining in the party, multiple vulnerabilities of Webex disclosed have put the security in danger, one resting in its insufficient validation of values within the recording files formatted as ARF (Advanced Recording Format). No workarounds are yet known to address this defect in the software updates released by Cisco. But an alternative video converter to convert ARF to MP4 could lend a hand.
What Is ARF
As an advanced recording scheme proprietary to WebEx, the ARF file serves as the most widely used format in WebEx network-based events, but due to insufficient validations, security issues are exposed in the ARF file:
An attacker could exploit the vulnerability by sending a user a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the targeted user.
Another is that carrying a large capacity to store literally all data generated during a conference, including audio, video, participant lists, and tables of content, etc. ARF sees a high degree of incompatibility with most multimedia players apart from Network-Recording Player, an application designed by WebEx to play back ARF files. This naturally raises the bar of post video editing work.
As thus, an optimal solution falls on an efficient ARF to MP4 converter.
Tips: For the uninitiated, in the October 2020 update, WebEx has standardized the recording format that all-new recordings in WebEx Meetings could be stored in MP4, presenting a wider choice of playback tools, better security, and a more effortless collaboration experience.
