Description
OpenClaw Windows Node before 2026.7.1 contains an incomplete validation vulnerability in system.execApprovals.set that accepts wildcard-executable rules and abusable system binaries like mshta, rundll32, and certutil. Remote callers can add broad allow rules to execute arbitrary commands on the Windows host through system.run without operator checks or user prompts.

AI Analysis

Impact

The vulnerability, identified as CWE-184, resides in the system.execApprovals.set capability where validation is incomplete, allowing wildcard executable rules such as mshta, rundll32, and certutil. Attackers can add broad allow rules that enable arbitrary command execution via system.run without any operator checks or user interaction, leading to remote code execution on the Windows host and compromising confidentiality, integrity, and availability.

Affected Systems

OpenClaw Windows Node software running any version prior to 2026.7.1 is vulnerable. The issue exists in the system.execApprovals.set capability within the OpenClaw.Windows.Node component.

Risk and Exploitability

The CVSS score of 8.7 indicates high severity. EPSS is not available, and the vulnerability is not listed in the CISA KEV catalog, but this does not preclude exploitation. The likely attack vector is a remote caller accessing the exposed system.execApprovals.set endpoint, possibly over the network, to inject a wildcard rule. Once the rule is accepted, the attacker can immediately invoke system.run to execute arbitrary commands on the host with the node's privileges.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade OpenClaw Windows Node to version 2026.7.1 or later to eliminate the validation flaw.
  • Restrict or disable remote access to the system.execApprovals.set interface, limiting it to trusted administrative hosts or roles.
  • Monitor execution logs for unexpected system.run invocations and isolate infected nodes if suspicious activity is detected.
