It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2010-2023 in the wild and no public exploit code.\n\nAffected product: Exim Exim. 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-2010-2023/ (Markdown: https://insights.sbomify.com/CVE-2010-2023/index.md)","id":"CVE-2010-2023","markdown":"https://insights.sbomify.com/CVE-2010-2023/index.md","name":"CVE-2010-2023","record":{"aliases":["DEBIAN-CVE-2010-2023","GHSA-qrcj-mq48-333m"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Exim mail server","requires_auth":"low_privilege","summary":"Local attackers can exploit a race condition in Exim's appendfile transport to gain privileges or cause denial of service when using world-writable sticky-bit mail directories.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"exim","vendor":"exim"}],"cvss":{"score":4.4,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"transports/appendfile.c in Exim before 4.72, when a world-writable sticky-bit mail directory is used, does not verify the st_nlink field of mailbox files, which allows local users to cause a denial of service or possibly gain privileges by creating a hard link to another user's file.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Race condition in n/a","id":"CVE-2010-2023","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"exim:exim","products":["exim:exim"],"type":"race_condition","year":"2010"},"n_packages":0,"n_references":18,"next":{"headline":"Race condition in n/a","id":"CVE-2010-2024"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2010-2022"},"products":["n/a"],"published":"2010-06-07","related":[{"cvss_score":9.8,"headline":"Use after free in Exim","id":"CVE-2026-45185","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":9.8,"headline":"Exim AUTH Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2023-42115","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2020-28017","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-28018","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2020-28020","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-28022","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-28024","kev_date_added":null,"published":"2021-05-06"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Local attackers can exploit a race condition in Exim's appendfile transport to gain privileges or cause denial of service when using world-writable sticky-bit mail directories.","url":"https://insights.sbomify.com/CVE-2010-2023/"}
