CVE-2025-41250 is a high-severity vulnerability identified in VMware vCenter versions 7.0 and 8.0. It is classified as a CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), specifically manifesting as an SMTP header injection vulnerability. The flaw allows a malicious actor who has non-administrative privileges but the ability to create scheduled tasks within vCenter to manipulate the notification emails sent for these tasks. By exploiting this vulnerability, the attacker can inject arbitrary commands or malicious payloads into the SMTP headers, potentially leading to command injection attacks. The CVSS v3.1 score of 8.5 reflects a high impact, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N), and a scope change (S:C). The impact primarily affects integrity (I:H) and availability (A:L), with no direct confidentiality loss (C:N). Although no known exploits are currently in the wild, the vulnerability's nature and ease of exploitation make it a significant risk. The lack of available patches at the time of publication increases the urgency for mitigation. This vulnerability is critical in environments where vCenter is used to manage virtual infrastructure, as it could allow attackers to execute unauthorized commands or disrupt scheduled task notifications, potentially leading to broader compromise or operational disruption within the virtualized environment.

For European organizations, the impact of CVE-2025-41250 can be substantial, especially for enterprises relying heavily on VMware vCenter for managing their virtualized infrastructure. The ability for a low-privileged user to inject commands via SMTP headers can lead to integrity breaches, such as unauthorized command execution or manipulation of system behavior. This could disrupt automated task notifications, potentially masking malicious activities or causing operational failures. In critical sectors like finance, healthcare, and government, where VMware vCenter is widely deployed, such disruptions could affect service availability and trustworthiness of system alerts. Additionally, the scope change in the CVSS vector indicates that exploitation could affect components beyond the initially compromised privileges, increasing the risk of lateral movement or privilege escalation within the environment. The lack of confidentiality impact suggests that direct data leakage is unlikely, but the integrity and availability impacts could still lead to significant operational and reputational damage. European organizations with strict regulatory requirements (e.g., GDPR) must consider the implications of such integrity and availability compromises on compliance and incident reporting.

Given the absence of official patches at the time of disclosure, European organizations should implement several specific mitigation strategies: 1) Restrict permissions tightly within VMware vCenter, ensuring that only trusted users have the ability to create scheduled tasks, thereby reducing the attack surface. 2) Monitor and audit scheduled task creation and notification email configurations for unusual or unauthorized changes, using SIEM tools to detect anomalies indicative of exploitation attempts. 3) Implement network-level controls to restrict SMTP traffic originating from vCenter servers to trusted mail relay servers, preventing direct external SMTP connections that could be abused. 4) Employ email security gateways capable of detecting and blocking malformed or suspicious SMTP headers to mitigate the impact of injected commands. 5) Consider temporarily disabling or limiting scheduled task notification emails until a patch is available, if operationally feasible. 6) Stay informed on VMware advisories and apply patches promptly once released. 7) Conduct internal penetration testing focusing on scheduled task functionalities to identify potential exploitation paths. These targeted measures go beyond generic advice by focusing on privilege management, monitoring, and network/email controls specific to the vulnerability's exploitation vector.
