{"id":"GHSA-qh9x-gcfh-pcrw","summary":"OpenZeppelin Contracts's ERC165Checker may revert instead of returning false","details":"### Impact\n\n`ERC165Checker.supportsInterface` is designed to always successfully return a boolean, and under no circumstance revert. However, an incorrect assumption about Solidity 0.8's `abi.decode` allows some cases to revert, given a target contract that doesn't implement EIP-165 as expected, specifically if it returns a value other than 0 or 1.\n\nThe contracts that may be affected are those that use `ERC165Checker` to check for support for an interface and then handle the lack of support in a way other than reverting.\n\n### Patches\n\nThe issue was patched in 4.7.1.\n\n### References\n\nhttps://github.com/OpenZeppelin/openzeppelin-contracts/pull/3552\n\n### For more information\n\nIf you have any questions or comments about this advisory, or need assistance deploying the fix, email us at [security@openzeppelin.com](mailto:security@openzeppelin.com).\n","aliases":["CVE-2022-31170"],"modified":"2023-11-01T04:59:00.196897Z","published":"2022-07-21T22:33:01Z","database_specific":{"nvd_published_at":"2022-07-22T04:15:00Z","cwe_ids":["CWE-20","CWE-252"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2022-07-21T22:33:01Z"},"references":[{"type":"WEB","url":"https://github.com/OpenZeppelin/openzeppelin-contracts/security/advisories/GHSA-qh9x-gcfh-pcrw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31170"},{"type":"WEB","url":"https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3552"},{"type":"PACKAGE","url":"https://github.com/OpenZeppelin/openzeppelin-contracts"}],"affected":[{"package":{"name":"@openzeppelin/contracts","ecosystem":"npm","purl":"pkg:npm/%40openzeppelin/contracts"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.0.0"},{"fixed":"4.7.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/07/GHSA-qh9x-gcfh-pcrw/GHSA-qh9x-gcfh-pcrw.json"}},{"package":{"name":"@openzeppelin/contracts-upgradeable","ecosystem":"npm","purl":"pkg:npm/%40openzeppelin/contracts-upgradeable"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.0.0"},{"fixed":"4.7.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/07/GHSA-qh9x-gcfh-pcrw/GHSA-qh9x-gcfh-pcrw.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
