Security News > 2020 > June > Zoom Patches Two Serious Vulnerabilities Found by Cisco Researchers
Members of Cisco's Talos threat intelligence and research group have identified two vulnerabilities in the Zoom client application that can allow a remote attacker to write files to the targeted user's system and possibly achieve arbitrary code execution.
CVE-2020-6109 is related to the way Zoom processes GIF image files.
According to Talos, the file would have a.gif extension but its content could be executable code or a script, which could aid the attacker in the exploitation of other vulnerabilities.
The attacker then sends the victim a code snippet via Zoom with the same file ID and the same details in the obj tag.
When Zoom sees that the file has already been downloaded, it will unzip the previously downloaded file to a location picked by the attacker - this can be nearly any folder.
