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-2020-12645 in the wild and no public exploit code.\n\nAffected product: Open-Xchange Open-Xchange Appsuite. 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-2020-12645/ (Markdown: https://insights.sbomify.com/CVE-2020-12645/index.md)","id":"CVE-2020-12645","markdown":"https://insights.sbomify.com/CVE-2020-12645/index.md","name":"CVE-2020-12645","record":{"aliases":["GHSA-9753-9pqh-vm76"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OX App Suite","requires_auth":"none","summary":"Attackers can cause denial of service in OX App Suite by exploiting improper input validation in rate limits via crafted headers and spoofed notices.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"open-xchange_appsuite","vendor":"open-xchange"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"OX App Suite 7.10.1 to 7.10.3 has improper input validation for rate limits with a crafted User-Agent header, spoofed vacation notices, and /apps/load memory consumption.","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":"Denial of service in n/a","id":"CVE-2020-12645","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"open-xchange:open-xchange_appsuite","products":["open-xchange:open-xchange_appsuite"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-12646"},"packages":[],"prev":{"headline":"Server-side request forgery in n/a","id":"CVE-2020-12644"},"products":["n/a"],"published":"2020-08-31","related":[{"cvss_score":9.9,"headline":"Server-side request forgery in n/a","id":"CVE-2017-13667","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2019-7158","kev_date_added":null,"published":"2019-06-17"},{"cvss_score":9.8,"headline":"Misconfiguration in n/a","id":"CVE-2017-17060","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2017-5210","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2017-5212","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2017-5863","kev_date_added":null,"published":"2019-05-22"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can cause denial of service in OX App Suite by exploiting improper input validation in rate limits via crafted headers and spoofed notices.","url":"https://insights.sbomify.com/CVE-2020-12645/"}
