Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21248 in the wild and no public exploit code.\n\nAffected product: theonedev onedev. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-21248/ (Markdown: https://insights.sbomify.com/CVE-2021-21248/index.md)","id":"CVE-2021-21248","markdown":"https://insights.sbomify.com/CVE-2021-21248/index.md","name":"CVE-2021-21248","record":{"aliases":["GHSA-gwp4-5498-hv5f"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"DevOps platform","requires_auth":"low_privilege","summary":"Authenticated users can execute arbitrary code on the server by injecting Groovy code into build parameters.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"onedev","vendor":"onedev_project"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Post-Auth Arbitrary Code execution via Groovy script injection","id":"CVE-2021-21248","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Post-Auth Unsafe Yaml deserialization","id":"CVE-2021-21249"},"packages":[],"prev":{"headline":"Post-Auth Unsafe Deserialization on BasePage (AJAX)","id":"CVE-2021-21247"},"products":["onedev"],"published":"2021-01-15","related":[{"cvss_score":10,"headline":"Pre-Auth Unsafe Deserialization on AttachmentUploadServet","id":"CVE-2021-21242","kev_date_added":null,"published":"2021-01-15"},{"cvss_score":10,"headline":"Pre-Auth Unsafe Deserialization on KubernetesResource","id":"CVE-2021-21243","kev_date_added":null,"published":"2021-01-15"},{"cvss_score":10,"headline":"Pre-Auth SSTI via Bean validation message tampering","id":"CVE-2021-21244","kev_date_added":null,"published":"2021-01-15"},{"cvss_score":10,"headline":"Pre-Auth Arbitrary File Upload","id":"CVE-2021-21245","kev_date_added":null,"published":"2021-01-15"},{"cvss_score":9.9,"headline":"CI/CD Docker Escape in OneDev","id":"CVE-2022-39206","kev_date_added":null,"published":"2022-09-13"},{"cvss_score":9.6,"headline":"Post-Auth Unsafe Deserialization on BasePage (AJAX)","id":"CVE-2021-21247","kev_date_added":null,"published":"2021-01-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["theonedev"]},"summary":"Authenticated users can execute arbitrary code on the server by injecting Groovy code into build parameters.","url":"https://insights.sbomify.com/CVE-2021-21248/"}
