CVE-2026-67261 in Virtual Storage Integrator for VMware vSphere Client
Summary
by MITRE • 08/06/2026
Dell Virtual Storage Integrator for VMware vSphere Client, versions prior to 10.11.1.0, contain(s) an OS Command Injection vulnerability in the IAPI component. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the application's underlying operating system with root privileges. Exploitation may lead to a complete system takeover by an attacker. This vulnerability is considered critical as it allows an unauthenticated remote attacker to achieve arbitrary code execution as root, potentially compromising the entire VSI deployment and underlying infrastructure. Dell recommends customers to upgrade at the earliest opportunity.

The Dell Virtual Storage Integrator for VMware vSphere Client represents a critical component in enterprise storage management environments where seamless integration between virtualized storage solutions and VMware infrastructure is essential. This vulnerability exists within the IAPI component which serves as an intermediary layer facilitating communication between the VSI client and underlying storage systems, making it a prime target for exploitation by malicious actors seeking to compromise the entire virtualization stack.
The core technical flaw manifests as an OS Command Injection vulnerability that occurs when user-supplied input is improperly sanitized before being processed by the IAPI component. This weakness allows an unauthenticated remote attacker to inject malicious commands directly into the system's command execution pipeline, bypassing normal authentication mechanisms and authorization controls. The vulnerability stems from insufficient input validation and sanitization practices within the application's codebase, creating a direct pathway for command injection attacks that can be exploited without requiring any prior credentials or access privileges.
The operational impact of this vulnerability extends far beyond simple data compromise, as successful exploitation grants attackers full root-level privileges on the underlying operating system hosting the VSI client. This elevated privilege level enables complete system takeover capabilities including but not limited to arbitrary code execution, privilege escalation, data exfiltration, and potential lateral movement within the network infrastructure. The critical nature of this vulnerability is underscored by its ability to compromise the entire virtual storage integration deployment and subsequently affect all underlying VMware vSphere infrastructure components that depend on secure communication with the VSI client.
From a cybersecurity perspective, this vulnerability aligns with CWE-77 and CWE-88 classification standards, representing command injection flaws that bypass input validation mechanisms through improper sanitization of user-supplied data. The ATT&CK framework categorizes this as a privilege escalation technique under T1068, where attackers leverage application vulnerabilities to gain elevated system privileges. Organizations utilizing Dell VSI components are particularly vulnerable because the attack vector requires no authentication, making it accessible to anyone with network connectivity to the affected systems. This unauthenticated access capability significantly amplifies the risk profile and requires immediate remediation to prevent potential widespread compromise of virtualized environments.
The recommended mitigation strategy centers on immediate upgrade to Dell Virtual Storage Integrator version 10.11.1.0 or later, which includes patched implementations addressing the input validation deficiencies that enabled command injection attacks. Organizations should also implement network segmentation and access controls to limit exposure of vulnerable components to untrusted networks while conducting thorough vulnerability assessments to identify any potential exploitation attempts. Additionally, monitoring for suspicious command execution patterns and implementing robust logging mechanisms will aid in early detection of attempted exploitation activities.
