An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2019-9670 in the wild since at least 10 Jan 2022.\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-2019-9670/ (Markdown: https://insights.sbomify.com/CVE-2019-9670/index.md)","id":"CVE-2019-9670","markdown":"https://insights.sbomify.com/CVE-2019-9670/index.md","name":"CVE-2019-9670","record":{"aliases":["GHSA-pj74-pf28-5qjw"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Zimbra Collaboration Suite","requires_auth":"none","summary":"An XML External Entity injection vulnerability in Zimbra's mailboxd component allows attackers to read sensitive files or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zimbra_collaboration_suite","vendor":"synacor"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"mailboxd component in Synacor Zimbra Collaboration Suite 8.7.x before 8.7.11p10 has an XML External Entity injection (XXE) vulnerability, as demonstrated by Autodiscover/Autodiscover.xml.","ecosystems":[],"exploits":{"exploitdb":4,"first_seen":"2019-03-13","github_poc":3,"max_poc_stars":26,"metasploit":1,"nuclei":1,"refs":[{"date":"2019-08-16T04:37:11Z","kind":"github_poc","ref":"https://github.com/rek7/Zimbra-RCE","stars":26,"title":"Zimbra RCE PoC -
