CVE-2026-101207: Dell OpenManage Integration RCE Vulnerability

CVE-2026-101207 Overview

CVE-2026-101207 is an OS Command Injection vulnerability [CWE-78] in Dell OpenManage Integration with Microsoft Windows Admin Center (OMIMSWAC) versions prior to 3.7.0. The flaw stems from improper neutralization of special elements passed to operating system commands. A low-privileged attacker with remote network access can inject arbitrary OS commands and achieve remote code execution on the host running the integration. Dell published advisory DSA-2026-442 to address the issue.

Critical Impact

A remote, low-privileged attacker can execute arbitrary operating system commands on the Windows Admin Center host, resulting in full compromise of confidentiality, integrity, and availability.

Affected Products

• Dell OpenManage Integration with Microsoft Windows Admin Center versions prior to 3.7.0
• Microsoft Windows Admin Center hosts running the vulnerable Dell OMIMSWAC extension
• Dell PowerEdge server management workflows that rely on the affected integration

Technical Details for CVE-2026-101207

Vulnerability Analysis

The vulnerability is classified as OS Command Injection under CWE-78. Dell OpenManage Integration with Microsoft Windows Admin Center passes user-controllable input into operating system command invocations without sufficient sanitization. An authenticated attacker with low privileges can embed shell metacharacters or additional command fragments inside request parameters. The injected commands execute in the security context of the integration process on the Windows Admin Center host.

Successful exploitation yields remote code execution. Because Windows Admin Center is commonly deployed to manage fleets of Dell PowerEdge servers, a single compromised instance can be used to pivot into managed infrastructure. The attack requires network access to the Admin Center service and valid, though low-privileged, credentials.

Root Cause

The root cause is improper neutralization of special elements used in an OS command. User-supplied data flows into a command execution sink without allowlist validation, parameterized APIs, or shell escaping. Specific function names and parameter paths are not disclosed in the public advisory.

Attack Vector

The attack vector is network based. An attacker authenticates to Windows Admin Center with a low-privileged account, then submits a crafted request to a vulnerable OMIMSWAC endpoint. The injected payload is appended to a backend command and executed by the host operating system. No user interaction is required beyond the attacker's own authenticated session.

No public proof-of-concept exploit is listed in CISA KEV or ExploitDB at the time of publication. The EPSS probability indicates a non-trivial likelihood of exploit development compared to the broader CVE population. Refer to the Dell Security Update DSA-2026-442 for vendor-specific technical details.

Detection Methods for CVE-2026-101207

Indicators of Compromise

• Unexpected child processes such as cmd.exe, powershell.exe, or wmic.exe spawned by the Windows Admin Center or OMIMSWAC process tree.
• Outbound network connections from the Admin Center host to unfamiliar external IPs following authenticated API calls to OMIMSWAC endpoints.
• Creation of new local accounts, scheduled tasks, or services on the host running Windows Admin Center shortly after OMIMSWAC activity.

Detection Strategies

• Hunt for process-lineage anomalies where OMIMSWAC or Windows Admin Center service processes spawn command interpreters or living-off-the-land binaries.
• Correlate authenticated OMIMSWAC HTTP requests containing shell metacharacters (;, &, |, backticks, $() with subsequent process creation events on the host.
• Review Windows Admin Center access logs for low-privileged accounts invoking Dell management actions outside of expected operational windows.

Monitoring Recommendations

• Enable Windows command-line process auditing (Event ID 4688 with command line logging) and PowerShell script block logging on Admin Center hosts.
• Forward Windows Admin Center, IIS, and OMIMSWAC logs to a centralized analytics platform for cross-source correlation.
• Alert on any execution of discovery tools (whoami, net, ipconfig, nltest) originating from the Admin Center service account.

How to Mitigate CVE-2026-101207

Immediate Actions Required

• Upgrade Dell OpenManage Integration with Microsoft Windows Admin Center to version 3.7.0 or later as directed by Dell advisory DSA-2026-442.
• Restrict network access to Windows Admin Center to trusted administrative subnets and jump hosts only.
• Audit and reduce the number of accounts with any role in Windows Admin Center, enforcing least privilege and multi-factor authentication.

Patch Information

Dell has released a fixed version of OMIMSWAC. Administrators should install version 3.7.0 or later. Full remediation guidance is available in the Dell Security Update DSA-2026-442 advisory.

Workarounds

• If immediate patching is not feasible, disable or uninstall the Dell OMIMSWAC extension within Windows Admin Center until the upgrade can be applied.
• Place Windows Admin Center behind a management VPN or privileged access workstation gateway to block untrusted authenticated users.
• Rotate credentials for any accounts that have logged into the Admin Center host and review recent audit logs for anomalous command execution.

# Example: verify installed OMIMSWAC version on the Admin Center host (PowerShell)
Get-WmiObject -Class Win32_Product | 
  Where-Object { $_.Name -like '*OpenManage Integration*Windows Admin Center*' } | 
  Select-Object Name, Version

# Example: remove the extension pending patch deployment
# (Run from an elevated PowerShell session on the Admin Center host)
Uninstall-Package -Name 'Dell OpenManage Integration with Microsoft Windows Admin Center' -Force
