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-2018-20433 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.mchange:c3p0 (Maven): affected all versions; fixed in 0.9.5.3\n- com.mchange:c3p0 (Maven): affected all versions; fixed in 0.9.5.3\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-2018-20433/ (Markdown: https://insights.sbomify.com/CVE-2018-20433/index.md)","id":"CVE-2018-20433","markdown":"https://insights.sbomify.com/CVE-2018-20433/index.md","name":"CVE-2018-20433","record":{"aliases":["DEBIAN-CVE-2018-20433","DLA-1621-1","GHSA-q485-j897-qc27","UBUNTU-CVE-2018-20433","openSUSE-SU-2024:10669-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java connection pool library","requires_auth":"none","summary":"An attacker can exploit an XML External Entity vulnerability in c3p0 during initialization 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":"debian_linux","vendor":"debian"},{"product":"c3p0","vendor":"mchange"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"c3p0 0.9.5.2 allows XXE in extractXmlConfigFromInputStream in com/mchange/v2/c3p0/cfg/C3P0ConfigXmlUtils.java during initialization.","ecosystems":["Maven","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":"2020-12-13","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2020-12-13T12:08:30Z","kind":"github_poc","ref":"https://github.com/shanika04/cp30_XXE_partial_fix","stars":0,"title":"version between CVE-2018-20433 and CVE-2019-5427"}],"tier":"poc_unverified"},"has_fix":true,"headline":"XML External Entity Reference in mchange:c3p0","id":"CVE-2018-20433","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"xxe","year":"2018"},"n_packages":3,"n_references":4,"next":{"headline":"LibreNMS arbitrary OS commands execution","id":"CVE-2018-20434"},"packages":[{"ecosystem":"Maven","fixed":["0.9.5.3"],"introduced":["0"],"last_affected":[],"package":"com.mchange:c3p0","purl":null,"source":"GHSA-q485-j897-qc27"},{"ecosystem":"Maven","fixed":["0.9.5.3"],"introduced":["0"],"last_affected":[],"package":"com.mchange:c3p0","purl":"pkg:maven/com.mchange/c3p0","source":"GHSA-q485-j897-qc27"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["0.9.5.5-1.3"],"introduced":["0"],"last_affected":[],"package":"c3p0","purl":"pkg:rpm/opensuse/c3p0\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:10669-1"}],"prev":{"headline":"Hardcoded credentials in n/a","id":"CVE-2018-20432"},"products":["n/a"],"published":"2018-12-24","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"An attacker can exploit an XML External Entity vulnerability in c3p0 during initialization to read sensitive files or cause denial of service.","url":"https://insights.sbomify.com/CVE-2018-20433/"}
