Improper authorization in Zoom Workplace's custom URL scheme handler allows unauthenticated attackers to escalate privileges via network access, requiring user interaction.
Vulnerability
The vulnerability resides in the handler for custom URL schemes in Zoom Workplace for Android before version 7.0.4 and for iOS before version 7.0.3. Due to improper authorization, an unauthenticated user can trigger an escalation of privilege via network access [1].
Exploitation
An attacker with network access must convince a user to interact with a maliciously crafted URL (user interaction is required, as indicated by the CVSS vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N). The attacker can exploit the improper authorization to perform actions with elevated privileges [1].
Impact
Successful exploitation results in high confidentiality and integrity impact, with no effect on availability (C:H/I:H/A:N). The attacker gains unauthorized access to sensitive information and the ability to modify data, effectively achieving privilege escalation [1].
Mitigation
Zoom has addressed this issue in Zoom Workplace version 7.0.4 for Android and version 7.0.3 for iOS. Users are advised to update to the latest available versions. No workarounds have been disclosed [1].
