An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-18985 in the wild and no public exploit code.\n\nAffected product: Synacor Zimbra Collaboration Suite. 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-2020-18985/ (Markdown: https://insights.sbomify.com/CVE-2020-18985/index.md)","id":"CVE-2020-18985","markdown":"https://insights.sbomify.com/CVE-2020-18985/index.md","name":"CVE-2020-18985","record":{"aliases":["GHSA-h95g-226g-7wq6"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Zimbra Collaboration","requires_auth":"none","summary":"Attackers can redirect users to arbitrary websites via the CalDAV service, potentially facilitating phishing attacks against Zimbra Collaboration users.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zimbra_collaboration_suite","vendor":"synacor"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"An issue in /domain/service/.ewell-known/caldav of Zimbra Collaboration 8.8.12 allows attackers to redirect users to any arbitrary website of their choosing.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Open redirect in n/a","id":"CVE-2020-18985","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"synacor:zimbra_collaboration_suite","products":["synacor:zimbra_collaboration_suite"],"type":"open_redirect","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-18998"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-18984"},"products":["n/a"],"published":"2021-12-15","related":[{"cvss_score":10,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Command Execution","id":"CVE-2024-45519","kev_date_added":"2024-10-03","published":"2024-10-02"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Arbitrary File Upload","id":"CVE-2022-41352","kev_date_added":"2022-10-20","published":"2022-09-26"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Authentication Bypass","id":"CVE-2022-37042","kev_date_added":"2022-08-11","published":"2022-08-11"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Command Injection","id":"CVE-2022-27924","kev_date_added":"2022-08-04","published":"2022-04-20"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Server-Side Request Forgery","id":"CVE-2020-7796","kev_date_added":"2026-02-17","published":"2020-02-18"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Improper Restriction of XML External Entity Reference","id":"CVE-2019-9670","kev_date_added":"2022-01-10","published":"2019-05-29"},{"cvss_score":9,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Cross-Site Scripting (XSS)","id":"CVE-2023-34192","kev_date_added":"2025-02-25","published":"2023-07-06"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can redirect users to arbitrary websites via the CalDAV service, potentially facilitating phishing attacks against Zimbra Collaboration users.","url":"https://insights.sbomify.com/CVE-2020-18985/"}
