{"id":"CVE-2021-21248","state":"PUBLISHED","title":"Post-Auth Arbitrary Code execution via Groovy script injection","description":"OneDev is an all-in-one devops platform. In OneDev before version 4.0.3, there is a critical vulnerability involving the build endpoint parameters. InputSpec is used to define parameters of a Build spec. It does so by using dynamically generated Groovy classes. A user able to control job parameters can run arbitrary code on OneDev's server by injecting arbitrary Groovy code. The ultimate result is in the injection of a static constructor that will run arbitrary code. For a full example refer to the referenced GHSA. This issue was addressed in 4.0.3 by escaping special characters such as quote from user input.","publishedAt":"2021-01-15T20:10:30.000Z","updatedAt":"2024-08-03T18:09:15.318Z","severity":{"score":9.6,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["theonedev onedev"],"affected":[{"vendor":"theonedev","product":"onedev","versions":[{"version":"< 4.0.3","status":"affected"}]}],"references":["https://github.com/theonedev/onedev/security/advisories/GHSA-gwp4-5498-hv5f","https://github.com/theonedev/onedev/commit/39d95ab8122c5d9ed18e69dc024870cae08d2d60"],"weaknesses":["CWE-74"],"ingestedAt":"2026-10-29T19:47:59.168Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/21xxx/CVE-2021-21248.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-21248","state":"PUBLISHED","datePublished":"2021-01-15T20:10:30.000Z","dateUpdated":"2024-08-03T18:09:15.318Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2020-12-22T00:00:00.000Z"},"containers":{"cna":{"title":"Post-Auth Arbitrary Code execution via Groovy script injection","descriptions":[{"lang":"en","value":"OneDev is an all-in-one devops platform.
