CVE-2025-58132 is a command injection vulnerability classified under CWE-77, found in Zoom Clients for Windows. This vulnerability stems from improper neutralization of special characters in command inputs, allowing an authenticated user to inject and execute arbitrary commands within the context of the Zoom client application. The flaw enables potential disclosure of sensitive information via network channels, though it does not directly affect system integrity or availability. Exploitation requires the attacker to have legitimate user credentials (privileged or non-privileged) and to perform some user interaction, such as triggering a vulnerable function within the client. The vulnerability is present in certain versions of the Zoom Windows client, though exact affected versions are not specified here. The CVSS v3.1 base score is 4.1, reflecting a medium severity with network attack vector, low attack complexity, and partial confidentiality impact. No public exploits or active exploitation campaigns have been reported as of the publication date. The vulnerability highlights the risk of command injection in widely deployed communication software, emphasizing the need for secure input validation and sanitization in client applications.

For European organizations, this vulnerability poses a moderate risk primarily to confidentiality, as it could allow an authenticated attacker to disclose sensitive information over the network. Given Zoom's extensive use in Europe for business and governmental communications, exploitation could lead to leakage of meeting details, user data, or internal configuration information. Although the vulnerability does not compromise system integrity or availability, the exposure of confidential information could facilitate further attacks or espionage. The requirement for authentication and user interaction limits the attack surface but does not eliminate risk, especially in environments with many users or where credential compromise is possible. Organizations in sectors such as finance, government, healthcare, and critical infrastructure that rely heavily on Zoom for communication may face increased risk. The absence of known exploits reduces immediate threat but should not lead to complacency. Attackers could develop exploits targeting this vulnerability, especially in targeted attacks against high-value European entities.

European organizations should implement the following specific mitigations: 1) Monitor Zoom client usage and network traffic for unusual command execution patterns or unexpected network disclosures. 2) Enforce strict access controls and multi-factor authentication to reduce the risk of credential compromise and unauthorized access. 3) Limit user privileges on endpoints running Zoom clients to the minimum necessary to reduce the impact of command injection. 4) Apply application whitelisting and endpoint detection and response (EDR) solutions to detect and block suspicious command execution attempts. 5) Stay alert for official Zoom security advisories and promptly apply patches or updates once released, as no patch links are currently available. 6) Conduct user awareness training to reduce risky user interactions that could trigger exploitation. 7) Consider network segmentation to isolate Zoom client traffic and sensitive internal resources. 8) Review and harden Zoom client configurations to disable unnecessary features or integrations that could be leveraged in exploitation.
