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-2018-1000823 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.exist-db:exist-core (Maven): affected all versions; fixed in 5.1.0\n- org.exist-db:exist-core (Maven): affected all versions; fixed in 5.1.0\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-2018-1000823/ (Markdown: https://insights.sbomify.com/CVE-2018-1000823/index.md)","id":"CVE-2018-1000823","markdown":"https://insights.sbomify.com/CVE-2018-1000823/index.md","name":"CVE-2018-1000823","record":{"aliases":["GHSA-jxm5-5xcw-h57q"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Exist REST Server","requires_auth":"none","summary":"An XML External Entity vulnerability in the Exist REST Server allows attackers to disclose confidential data, cause denial of service, or perform SSRF.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"exist","vendor":"exist-db"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"exist version \u003c= 5.0.0-RC4 contains a XML External Entity (XXE) vulnerability in XML Parser for REST Server that can result in Disclosure of confidential data, denial of service, SSRF, port scanning.","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":"exist-db:exist-core XML External Entity (XXE) vulnerability","id":"CVE-2018-1000823","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xxe","year":"2018"},"n_packages":2,"n_references":2,"next":{"headline":"Deserialization in n/a","id":"CVE-2018-1000824"},"packages":[{"ecosystem":"Maven","fixed":["5.1.0"],"introduced":["0"],"last_affected":[],"package":"org.exist-db:exist-core","purl":null,"source":"GHSA-jxm5-5xcw-h57q"},{"ecosystem":"Maven","fixed":["5.1.0"],"introduced":["0"],"last_affected":[],"package":"org.exist-db:exist-core","purl":"pkg:maven/org.exist-db/exist-core","source":"GHSA-jxm5-5xcw-h57q"}],"prev":{"headline":"XML External Entity (XXE) vulnerability in codelibs fess","id":"CVE-2018-1000822"},"products":["n/a"],"published":"2018-12-20","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 XML External Entity vulnerability in the Exist REST Server allows attackers to disclose confidential data, cause denial of service, or perform SSRF.","url":"https://insights.sbomify.com/CVE-2018-1000823/"}
