Inspektor Gadget has a Command Injection vulnerability in Makefile.build

6.6 MediumFix available

Inspektor Gadget is a set of tools and framework for data collection and system inspection on Kubernetes clusters and Linux hosts using eBPF. The ig binary provides a subcommand for image building, used to generate custom gadget OCI images. A part of this functionality is implemented in the file inspektor-gadget/cmd/common/image/build.go. The Makefile.build file is the Makefile template employed during the building process. This file includes user-controlled data in an unsafe fashion, specifically some parameters are embedded without an adequate escaping in the commands inside the Makefile. Prior to version 0.48.1, this implementation is vulnerable to command injection: an attacker able to control values in the buildOptions structure would be able to execute arbitrary commands during the building process. An attacker able to exploit this vulnerability would be able to execute arbitrary command on the Linux host where the ig command is launched, if images are built with the --local flag or on the build container invoked by ig, if the --local flag is not provided. The buildOptions structure is extracted from the YAML gadget manifest passed to the ig image build command. Therefore, the attacker would need a way to control either the full build.yml file passed to the ig image build command, or one of its options. Typically, this could happen in a CI/CD scenario that builds untrusted gadgets to verify correctness. Version 0.51.1 fixes the issue.

Inspektor Gadget: Command Injection via malicious buildOptions manipulation

Impacted Resources

inspektor-gadget/cmd/common/image/build.go inspektor-gadget/cmd/common/image/helpers/Makefile.build

Description

The ig binary provides a subcommand for image building, used to generate custom gadget OCI images.

A part of this functionality is implemented in the file inspektor-gadget/cmd/common/image/build.go.

The following is the code responsible to construct the build command:

func buildCmd(options buildOptions) []string {
	cmd := []string{
		"make", "-f", filepath.Join(options.outputDir, "Makefile.build"),
		"-j", fmt.Sprintf("%d", runtime.NumCPU()),
		"OUTPUTDIR=" + options.outputDir,
		"CFLAGS=" + options.cFlags,
		"FORCE_COLORS=" + options.forceColorsFlag,
	}

	if options.ebpfSourcePath != "" {
		cmd = append(cmd, "EBPFSOURCE="+options.ebpfSourcePath, "ebpf")
	}
	if options.wasmSourcePath != "" {
		cmd = append(cmd, "WASM="+options.wasmSourcePath, "wasm")
	}
	if options.btfgen {
		cmd = append(cmd, "BTFHUB_ARCHIVE="+options.btfHubArchivePath, "btfgen")
	}

	return cmd
}

The Makefile.build file is the Makefile template employed during the building process.

This file includes user-controlled data in an unsafe fashion, specifically some parameters are embedded without an adequate escaping in the commands inside the Makefile.

This implementation is vulnerable to command injection: an attacker able to control values in the buildOptions structure would be able to execute arbitrary commands during the building process.

Impact

An attacker able to exploit this vulnerability would be able to execute arbitray command:

  • on the Linux host where the ig command is launched, if images are built with the --local flag
  • on the build container invoked by ig, if the --local flag is not provided

Attack Complexity

The buildOptions structure is extracted from the YAML gadget manifest passed to the ig image build command. Therefore, the attacker would need a way to control either the full build.yml file passed to the ig image build command, or one of its options.

Typically, this could happen in a CI/CD scenario that builds untrusted gadgets to verify correctness.
