Affected packages
• Go github.com/karmada-io/karmada: < 1.12.0 → fixed in 1.12.0
Description
Impact
_What kind of vulnerability is it? Who is impacted?_
Both in karmadactl and karmada-operator, it is possible to supply a filesystem path, or an HTTP(s) URL to retrieve the custom resource definitions(CRDs) needed by karmada. The CRDs are downloaded as a gzipped tarfile and are vulnerable to a TarSlip vulnerability. An attacker able to supply a malicious CRD file into a karmada initialization could write arbitrary files in arbitrary paths of the filesystem.
Patches
_Has the problem been patched? What versions should users upgrade to?_
From karmada version v1.12.0, when processing custom CRDs files, CRDs archive verification is utilized to enhance file system robustness.
Workarounds
_Is there a way for users to fix or remediate the vulnerability without upgrading?_
When using `karmadactl init` to set up Karmada, if you need to set flag `--crd` to customize the CRD files required for karmada initialization, you can manually inspect the CRD files to check whether they contain sequences such as `../` that would alter file paths, to determine if they potentially include malicious files.
When using karmada-operator to set up Karmada, you must upgrade your karmada-operator to one of the fixed versions.
