CVE-2022-31156

Current Description

Gradle is a build tool. Dependency verification is a security feature in Gradle Build Tool that was introduced to allow validation of external dependencies either through their checksum or cryptographic signatures. In versions 6.2 through 7.4.2, there are some cases in which Gradle may skip that verification and accept a dependency that would otherwise fail the build as an untrusted external artifact. This can occur in two ways. When signature verification is disabled but the verification metadata contains entries for dependencies that only have a `gpg` element but no `checksum` element. When signature verification is enabled, the verification metadata contains entries for dependencies with a `gpg` element but there is no signature file on the remote repository. In both cases, the verification will accept the dependency, skipping signature verification and not complaining that the dependency has no checksum entry. For builds that are vulnerable, there are two risks. Gradle could download a malicious binary from a repository outside your organization due to name squatting. For those still using HTTP only and not HTTPS for downloading dependencies, the build could download a malicious library instead of the expected one. Gradle 7.5 patches this issue by making sure to run checksum verification if signature verification cannot be completed, whatever the reason. Two workarounds are available: Remove all `gpg` elements from dependency verification metadata if you disable signature validation and/or avoid adding `gpg` entries for dependencies that do not have signature files.

Severity

CVSS 3.x Severity and Metrics:

NIST: NVD

Base Score: 4.4 MEDIUM

Vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:N

Nist CVSS score does not match with CNA score

CNA: GitHub, Inc.

Base Score: 6.6 MEDIUM

Vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
