Why It Matters

Analysis dossier

Why It Matters

A flaw was found in Foreman. A remote attacker could exploit a command injection vulnerability in Foreman's WebSocket proxy implementation. This vulnerability arises from the system's use of unsanitized hostname values from compute resource providers when constructing shell commands. By operating a malicious compute resource server, an attacker could achieve remote code execution on the Foreman server when a user accesses VM VNC console functionality. This could lead to the compromise of sensitive credentials and the entire managed infrastructure.

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
Show more (2)

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
