{"id":"GHSA-2x52-8f29-7cjr","summary":"Eclipse Dataspace Components vulnerable to OAuth2 client secret disclosure","details":"In Eclipse Dataspace Components from version 0.2.1 to 0.6.2, in the [EDC Connector component](https://github.com/eclipse-edc/Connector), an attacker might obtain OAuth2 client secrets from the vault.\n\nIn Eclipse Dataspace Components from version 0.2.1 to 0.6.2, we have identified a security vulnerability in the EDC Connector component ( https://github.com/eclipse-edc/Connector ) regarding the OAuth2-protected data sink feature. When using a custom, OAuth2-protected data sink, the OAuth2-specific data address properties are resolved by the provider data plane. Problematically, the consumer-provided clientSecretKey, which indicates the OAuth2 client secret to retrieve from a secrets vault, is resolved in the context of the provider's vault, not the consumer. This secret's value is then sent to the tokenUrl, also consumer-controlled, as part of an OAuth2 client credentials grant. The returned access token is then sent as a bearer token to the data sink URL.\n\nThis feature is now disabled entirely, because not all code paths necessary for a successful realization were fully implemented.","aliases":["CVE-2024-4536"],"modified":"2025-02-06T19:49:31.844270Z","published":"2024-05-07T15:30:36Z","database_specific":{"cwe_ids":["CWE-201","CWE-522"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2024-05-07T16:51:10Z","nvd_published_at":"2024-05-07T13:15:48Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-4536"},{"type":"WEB","url":"https://github.com/eclipse-edc/Connector/commit/a4e6018d2c0457fba6f672fafa6c590513c45d1b"},{"type":"PACKAGE","url":"https://github.com/eclipse-edc/Connector"},{"type":"WEB","url":"https://github.com/eclipse-edc/Connector/releases/tag/v0.6.3"},{"type":"WEB","url":"https://gitlab.eclipse.org/security/cve-assignement/-/issues/22"},{"type":"WEB","url":"https://gitlab.eclipse.org/security/vulnerability-reports/-/issues/198"}],"affected":[{"package":{"name":"org.eclipse.edc:connector-core","ecosystem":"Maven","purl":"pkg:maven/org.eclipse.edc/connector-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.2.1"},{"fixed":"0.6.3"}]}],"versions":["0.2.1","0.3.0","0.3.1","0.4.0","0.4.1","0.5.0","0.5.1","0.6.0","0.6.1","0.6.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-2x52-8f29-7cjr/GHSA-2x52-8f29-7cjr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:L"}]}
