How the Exploit Works
The vulnerability resides in the installer of the Zoom Workplace for Windows. An authenticated local user can leverage this flaw due to missing authorization checks. By exploiting this vulnerability, the attacker can conduct an escalation of privilege attack, gaining higher-level access rights on the system. This could potentially lead to system compromise and data leakage.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited. Please note that this is a theoretical example and not actual exploit code:
# Assume the attacker is already authenticated
$ echo "Exploit payload" > malicious_script.sh
# Run the Zoom Workplace installer with the payload
$ ./ZoomInstaller.exe --script malicious_script.shIn this theoretical scenario, the attacker creates a malicious script. They then run the installer with the malicious script, exploiting the missing authorization check to escalate their privileges.
Mitigation
Users are advised to update their Zoom Workplace for Windows on ARM to version 6.5.0 or later where this vulnerability has been fixed. As a temporary mitigation, usage of Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can help detect and prevent exploitation attempts.
