Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In Github.com/gardener/gardenctl v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A security vulnerability was discovered in [gardenctl](https://github.com/gardener/gardenctl-v2) when it is used with non‑POSIX shells such as **[Fish](https://fishshell.com/)** and **[PowerShell](https://learn.microsoft.com/en-us/powershell/)**. Such setup could allow an attacker with administrative privileges for a Gardener project to craft malicious credential values in infrastructure Secret objects that break out of the intended string context when evaluated in Fish or PowerShell environments used by the Gardener service operators, leading to arbitrary command execution on the operator's device. **Am I vulnerable?** This CVE affects all Gardener operators who use **gardenctl < v2.12.0** with non‑POSIX shells such as **[Fish](https://fishshell.com/)** and **[PowerShell](https://learn.microsoft.com/en-us/powershell/)**.
