CVE-2025-62484 is a vulnerability identified in Zoom Communications Inc.'s Zoom Workplace client software versions prior to 6.5.10. The root cause is inefficient regular expression complexity (classified under CWE-1333), which can be exploited by an unauthenticated attacker over the network to escalate privileges. This type of vulnerability typically arises when a regular expression used in input validation or processing is crafted in a way that causes excessive backtracking or computational overhead, potentially leading to denial of service or enabling attackers to manipulate program logic to gain higher privileges. In this case, the vulnerability allows an attacker to escalate privileges without authentication, though user interaction is required, indicating some form of social engineering or user-triggered action is necessary to complete exploitation. The CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N) indicates that the attack can be performed remotely without privileges and with low attack complexity, but requires user interaction. The impact on confidentiality and integrity is high, meaning attackers could access sensitive information or alter data, but availability is not affected. No patches or exploits are currently publicly available, but the vulnerability is officially published and should be addressed promptly. The affected product, Zoom Workplace, is widely used in enterprise environments for collaboration and communication, making this vulnerability a significant concern for organizational security.

The vulnerability allows an unauthenticated attacker to escalate privileges on Zoom Workplace clients, potentially gaining unauthorized access to sensitive communications, files, or administrative functions. This can lead to data breaches, unauthorized data modification, and compromise of user accounts or enterprise resources integrated with Zoom Workplace. Since Zoom Workplace is used globally for business collaboration, exploitation could disrupt organizational workflows and expose confidential corporate information. The requirement for user interaction suggests phishing or social engineering could be vectors, increasing the risk of targeted attacks. Although availability is not impacted, the high confidentiality and integrity impact can severely damage organizational trust and compliance posture. Enterprises relying heavily on Zoom Workplace for internal communications are at risk of espionage, data theft, and unauthorized control over collaboration environments if this vulnerability is exploited.

Organizations should immediately verify their Zoom Workplace client versions and upgrade all instances to version 6.5.10 or later once available. Until patches are applied, network-level controls such as firewall rules should restrict access to Zoom Workplace client network endpoints from untrusted sources. Implement strict email and communication security policies to reduce the risk of social engineering attacks that could trigger the required user interaction. Monitor network traffic and endpoint logs for unusual activity related to Zoom Workplace processes or unexpected privilege escalations. Employ endpoint detection and response (EDR) solutions to detect anomalous behavior indicative of exploitation attempts. Conduct user awareness training focused on recognizing phishing or suspicious prompts related to Zoom Workplace. Coordinate with Zoom Communications for timely patch releases and advisories. Consider isolating Zoom Workplace clients in segmented network zones to limit lateral movement if compromise occurs.
