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-2014-2957 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-2014-2957/ (Markdown: https://insights.sbomify.com/CVE-2014-2957/index.md)","id":"CVE-2014-2957","markdown":"https://insights.sbomify.com/CVE-2014-2957/index.md","name":"CVE-2014-2957","record":{"aliases":["DEBIAN-CVE-2014-2957","GHSA-r2xw-4p4f-wp3m","UBUNTU-CVE-2014-2957"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Exim mail server","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Exim mail servers with DMARC enabled by sending a malicious email with a crafted From header.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"exim","vendor":"exim"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The dmarc_process function in dmarc.c in Exim before 4.82.1, when EXPERIMENTAL_DMARC is enabled, allows remote attackers to execute arbitrary code via the From header in an email, which is passed to the expand_string function.","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":"Code injection in n/a","id":"CVE-2014-2957","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"exim:exim","products":["exim:exim"],"type":"code_injection","year":"2014"},"n_packages":0,"n_references":3,"next":{"headline":"Command injection in n/a","id":"CVE-2014-2959"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2014-2956"},"products":["n/a"],"published":"2014-09-04","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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code on Exim mail servers with DMARC enabled by sending a malicious email with a crafted From header.","url":"https://insights.sbomify.com/CVE-2014-2957/"}
