Details

Credential disclosure in syft when SYFT_ATTEST_PASSWORD environment variable set A password disclosure flaw was found in Syft versions v0.69.0 and v0.69.1. This flaw leaks the password stored in the SYFT_ATTEST_PASSWORD environment variable. ### Impact The `SYFT_ATTEST_PASSWORD` environment variable is for the `syft attest` command to generate attested SBOMs for the given container image. This environment variable is used to decrypt the private key (provided with `syft attest --key <path-to-key-file>`) during the signing process while generating an SBOM attestation. This vulnerability affects users running syft that have the `SYFT_ATTEST_PASSWORD` environment variable set with credentials (regardless of if the attest command is being used or not). Users that do not have the environment variable `SYFT_ATTEST_PASSWORD` set are not affected by this issue. The credentials are leaked in two ways: - in the syft logs when `-vv` or `-vvv` are used in the syft command (which is any log level >= `DEBUG`) - in the attestation or SBOM only when the `syft-json` format is used Note that as of v0.69.0 any generated attestations by the `syft attest` command are uploaded to the OCI registry (if you have write access to that registry) in the same way `cosign attach` is done. This means that any attestations generated for the affected versions of syft when the `SYFT_ATTEST_PASSWORD` environment variable was set would leak credentials in the attestation payload uploaded to the OCI registry. Example commands run from affected versions of syft that show the credential disclosure: ```bash $ SYFT_ATTEST_PASSWORD=123456 syft <container-image-or-directory-input> -o syft-json | grep 123456 # "123456" is in the output $ SYFT_ATTEST_PASSWORD=123456 syft attest <container-image-input> -o syft-json $ cosign download attestation <container-image-input> | jq -r '.payload' | base64 -d | grep 123456 # "123456" is in the output ``` ### Patches The patch has been released in v0.70.0. ### Workarounds There are no workarounds for this vulnerability. ### References Patch pull request: https://github.com/anchore/syft/pull/1538
