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. References _Are there any links users can visit to find out more?_ 1.
