Security readout for executives and security teams
Plain-English summary
An authenticated user with limited privileges could submit a crafted Kubernetes configuration that makes a Prowler App worker run an attacker-chosen operating-system command. Because workers may be shared, compromise could expose data, alter operations, or disrupt service beyond the initiating user’s scope.
Executive priority
Treat as an immediate remediation priority for affected Prowler App deployments, especially multi-user or shared-worker environments. Upgrade promptly and investigate historical provider connection activity because successful exploitation could compromise confidentiality, integrity, and availability.
Technical view
Before Prowler 5.36.0, validation checked Kubernetes exec authentication but missed legacy GCP auth-provider cmd-path settings. During provider connection testing, kubernetes-python processed that setting and launched the supplied command through subprocess.Popen on the worker. This is CWE-78 command injection with a CVSS 3.1 score of 9.9.
Likely exposure
Prowler deployments below 5.36.0 are potentially exposed when users can submit Kubernetes kubeconfig content and invoke the provider connection test. CVSS indicates network access and low privileges are required, with no user interaction. Internet exposure is not established by the supplied evidence.
Exploitation context
The supplied sources do not report active exploitation, and this CVE is not identified as being in KEV. Exploitation requires authenticated, low-privilege access to the relevant API workflow. Successful exploitation executes commands on a shared application worker, creating possible cross-scope impact.
Researcher notes
The root cause was incomplete unsafe-authentication detection: kubeconfig_contains_exec_auth inspected exec blocks but omitted legacy GCP auth-provider command fields. The vulnerable connection path loaded attacker-controlled configuration through load_kube_config_from_dict, reaching CommandTokenSource and subprocess.Popen. The supplied evidence establishes the flaw and fix, but not real-world exploitation.
Mitigation direction
- Upgrade Prowler to version 5.36.0 or later as the primary remediation.
- Until upgraded, restrict Kubernetes provider configuration and connection testing to trusted administrators.
- Follow the vendor advisory for any additional deployment-specific guidance.
Validation and detection
- Inventory Prowler App deployments and confirm every running component is version 5.36.0 or later.
- Review stored Kubernetes configurations for legacy GCP auth-provider entries containing cmd-path or cmd-args.
- Review worker and API telemetry for unusual processes associated with Kubernetes provider connection tests.
- Confirm the upgraded application rejects unsafe legacy command-based authentication configurations.

CWE-78: Command execution behavior lookup
Command injection weaknesses can lead defenders to review execution techniques and command interpreter telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupExecution behavior lookup
The CVE wording references code or command execution, so execution technique review may help defensive triage. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
Open ATT&CK lookupCredential and access behavior lookup
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
