An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-39205 exists.\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-2022-39205/ (Markdown: https://insights.sbomify.com/CVE-2022-39205/index.md)","id":"CVE-2022-39205","markdown":"https://insights.sbomify.com/CVE-2022-39205/index.md","name":"CVE-2022-39205","record":{"aliases":["GHSA-4f9h-h82c-4xm2"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"Git server","requires_auth":"none","summary":"Unauthenticated attackers can bypass access controls to execute arbitrary code on Onedev instances lacking proper reverse proxy configuration.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"onedev","vendor":"onedev_project"}],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Onedev is an open source, self-hosted Git Server with CI/CD and Kanban. In versions of Onedev prior to 7.3.0 unauthenticated users can take over a OneDev instance if there is no properly configured reverse proxy. The /git-prereceive-callback endpoint is used by the pre-receive git hook on the server to check for branch protections during a push event. It is only intended to be accessed from localhost, but the check relies on the X-Forwarded-For header. Invoking this endpoint leads to the execution of one of various git commands. The environment variables of this command execution can be controlled via query parameters. This allows attackers to write to arbitrary files, which can in turn lead to the execution of arbitrary code. Such an attack would be very hard to detect, which increases the potential impact even more. Users are advised to upgrade. There are no known workarounds for this issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Access Control Bypass in Onedev","id":"CVE-2022-39205","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2022"},"n_packages":0,"n_references":4,"next":{"headline":"CI/CD Docker Escape in OneDev","id":"CVE-2022-39206"},"packages":[],"prev":{"headline":"Parsing issue in matrix-org/node-irc leading to room takeovers","id":"CVE-2022-39203"},"products":["onedev"],"published":"2022-09-13","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"},{"cvss_score":9.6,"headline":"Post-Auth Arbitrary Code execution via Groovy script injection","id":"CVE-2021-21248","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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-22","vendors":["theonedev"]},"summary":"Unauthenticated attackers can bypass access controls to execute arbitrary code on Onedev instances lacking proper reverse proxy configuration.","url":"https://insights.sbomify.com/CVE-2022-39205/"}
