An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-38457 in the wild and no public exploit code.\n\nAffected product: AUVESY Versiondog. 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-2021-38457/ (Markdown: https://insights.sbomify.com/CVE-2021-38457/index.md)","id":"CVE-2021-38457","markdown":"https://insights.sbomify.com/CVE-2021-38457/index.md","name":"CVE-2021-38457","record":{"aliases":["GHSA-8mj9-mw5f-ccv3"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Version Control Server","requires_auth":"none","summary":"Attackers can access the AUVESY Versiondog server without authentication, potentially reading sensitive data or initiating unauthorized sessions.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"versiondog","vendor":"auvesy"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"The server permits communication without any authentication procedure, allowing the attacker to initiate a session with the server without providing any form of authentication.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"AUVESY Versiondog","id":"CVE-2021-38457","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Moxa MXview Network Management Software","id":"CVE-2021-38458"},"packages":[],"prev":{"headline":"Moxa MXview Network Management Software","id":"CVE-2021-38456"},"products":["Versiondog"],"published":"2021-10-22","related":[{"cvss_score":9.8,"headline":"AUVESY Versiondog","id":"CVE-2021-38449","kev_date_added":null,"published":"2021-10-22"},{"cvss_score":9.8,"headline":"AUVESY Versiondog","id":"CVE-2021-38477","kev_date_added":null,"published":"2021-10-22"},{"cvss_score":9.1,"headline":"AUVESY Versiondog","id":"CVE-2021-38453","kev_date_added":null,"published":"2021-10-22"},{"cvss_score":9.1,"headline":"AUVESY Versiondog","id":"CVE-2021-38469","kev_date_added":null,"published":"2021-10-22"},{"cvss_score":9.1,"headline":"AUVESY Versiondog","id":"CVE-2021-38471","kev_date_added":null,"published":"2021-10-22"},{"cvss_score":8.2,"headline":"AUVESY Versiondog","id":"CVE-2021-38461","kev_date_added":null,"published":"2021-10-22"}],"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":"2024-09-16","vendors":["AUVESY"]},"summary":"Attackers can access the AUVESY Versiondog server without authentication, potentially reading sensitive data or initiating unauthorized sessions.","url":"https://insights.sbomify.com/CVE-2021-38457/"}
