Summary

Details

Gradle is a build tool with a focus on build automation and support for multi-language development. This is a collision attack on long IDs (64bits) for PGP keys. Users of dependency verification in Gradle are vulnerable if they use long IDs for PGP keys in a trusted-key or pgp element in their dependency verification metadata file. The fix is to fail dependency verification if anything but a fingerprint is used in a trust element in dependency verification metadata. The problem is fixed in Gradle 8.0 and above. The problem is also patched in Gradle 6.9.4 and 7.6.1. As a workaround, use only full fingerprint IDs for trusted-key or pgp element in the metadata is a protection against this issue.

Title

Gradle usage of long IDs for PGP keys opens potential for collision attacks

Summary

Gradle is a build tool with a focus on build automation and support for multi-language development. This is a collision attack on long IDs (64bits) for PGP keys. Users of dependency verification in Gradle are vulnerable if they use long IDs for PGP keys in a `trusted-key` or `pgp` element in their dependency verification metadata file. The fix is to fail dependency verification if anything but a fingerprint is used in a trust element in dependency verification metadata. The problem is fixed in Gradle 8.0 and above. The problem is also patched in Gradle 6.9.4 and 7.6.1. As a workaround, use only full fingerprint IDs for `trusted-key` or `pgp` element in the metadata is a protection against this issue.

          "value": "Gradle is a build tool with a focus on build automation and support for multi-language development. This is a collision attack on long IDs (64bits) for PGP keys. Users of dependency verification in Gradle are vulnerable if they use long IDs for PGP keys in a `trusted-key` or `pgp` element in their dependency verification metadata file. The fix is to fail dependency verification if anything but a fingerprint is used in a trust element in dependency verification metadata. The problem is fixed in Gradle 8.0 and above. The problem is also patched in Gradle 6.9.4 and 7.6.1. As a workaround, use only full fingerprint IDs for `trusted-key` or `pgp` element in the metadata is a protection against this issue."

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
