Why It Matters

Analysis dossier

Why It Matters

open 7.2.0 before 11.0.0 contains an OS command injection vulnerability that allows attackers to execute PowerShell code by supplying crafted URLs on Windows and WSL. Attackers can embed $(...) subexpressions in URLs, such as OAuth authorization_endpoint values from malicious MCP servers, which execute when index.js passes them unescaped to powershell -EncodedCommand.

Suggested hunting (rule-based inference)

SecOps Signal recommendation (rule-based inference). These steps are hunting hypotheses from the vulnerability class; they do not state or imply that exploitation occurred here or anywhere.

Matched command-injection (CWE-78); user-interaction-client (CVSS AV:N, CVSS UI:R)

Exposure

  1. Identify installations of the affected product and compare versions with the advisory.Telemetry: DeviceTvmSoftwareVulnerabilities · A weakness class does not establish local exposure. · Rule command-injection
  2. Identify endpoints reporting this CVE, especially those used for email and web browsing.Telemetry: DeviceTvmSoftwareVulnerabilities · A network vector that needs user interaction points at user-facing client software. · Rule user-interaction-client

Exploitation evidence

  1. Review command interpreters spawned by the affected service or application.Telemetry: DeviceProcessEvents · Unexpected process lineage can support command-injection hunting. · Rule command-injection

Exploitation evidence

  1. Review unusual child processes started by the affected client application on affected endpoints.Telemetry: DeviceProcessEvents · Hunting hypothesis from the CVSS vector; it does not show that exploitation occurred. · Rule user-interaction-client

Response

  1. Confirm the vendor mitigation or fixed version on affected assets.Telemetry: DeviceTvmSoftwareVulnerabilities · Inventory checks can verify remediation. · Rule command-injection
