Vulnerability Details
CVE-2025-30663 describes a time-of-check time-of-use race condition that allows an authenticated user to conduct an escalation of privilege through local access. The vulnerability affects multiple Zoom products, including the meeting software development kit, rooms, rooms controller, workplace, workplace desktop, and workplace virtual desktop infrastructure. The CVSS score is 8.8, indicating a high severity level, and it has been categorized under CWE-367.
Technical Analysis
The root cause of this vulnerability lies in the race condition that occurs during the time of check and time of use. The attack vector is local, meaning that an attacker would need local access to exploit the vulnerability. The attack complexity is low, requiring only low privileges, and there is no user interaction necessary. The confidentiality, integrity, and availability impacts are all classified as high, emphasizing the potential for significant damage if the vulnerability is exploited.
Risk & Impact Analysis
Risk to organizations includes unauthorized privilege escalation, which can lead to data breaches or loss of control over critical systems. Given the wide deployment of Zoom products in various sectors, the blast radius of this vulnerability is significant. Organizations should assess their exposure and prioritize remediation based on the CVSS score and the potential impact on their operations.
