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-2018-20000 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.bedework:bw-webdav (Maven): affected from 4.0.1; fixed in 4.0.3\n- org.bedework:bw-webdav (Maven): affected from 4.0.1; fixed in 4.0.3\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-2018-20000/ (Markdown: https://insights.sbomify.com/CVE-2018-20000/index.md)","id":"CVE-2018-20000","markdown":"https://insights.sbomify.com/CVE-2018-20000/index.md","name":"CVE-2018-20000","record":{"aliases":["GHSA-5p52-j8pw-j7x5"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Bedework webdav","requires_auth":"none","summary":"An attacker can exploit an XML External Entity vulnerability in Bedework to read local files via a crafted invite-reply document.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"bw-webdav","vendor":"apereo"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"Apereo Bedework bw-webdav before 4.0.3 allows XXE attacks, as demonstrated by an invite-reply document that reads a local file, related to webdav/servlet/common/MethodBase.java and webdav/servlet/common/PostRequestPars.java.","ecosystems":["Maven"],"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":"Improper Restriction of XML External Entity Reference in bedework:bw-webdav","id":"CVE-2018-20000","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xxe","year":"2018"},"n_packages":2,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2018-20001"},"packages":[{"ecosystem":"Maven","fixed":["4.0.3"],"introduced":["4.0.1"],"last_affected":[],"package":"org.bedework:bw-webdav","purl":null,"source":"GHSA-5p52-j8pw-j7x5"},{"ecosystem":"Maven","fixed":["4.0.3"],"introduced":["4.0.1"],"last_affected":[],"package":"org.bedework:bw-webdav","purl":"pkg:maven/org.bedework/bw-webdav","source":"GHSA-5p52-j8pw-j7x5"}],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2018-19999"},"products":["n/a"],"published":"2018-12-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-09-16","vendors":["n/a"]},"summary":"An attacker can exploit an XML External Entity vulnerability in Bedework to read local files via a crafted invite-reply document.","url":"https://insights.sbomify.com/CVE-2018-20000/"}
