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-2018-13439 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.github.wxpay:wxpay-sdk (Maven): affected all versions up to 3; no fix listed\n- com.github.wxpay:wxpay-sdk (Maven): affected all versions up to 3; no fix listed\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-2018-13439/ (Markdown: https://insights.sbomify.com/CVE-2018-13439/index.md)","id":"CVE-2018-13439","markdown":"https://insights.sbomify.com/CVE-2018-13439/index.md","name":"CVE-2018-13439","record":{"aliases":["GHSA-gqgv-2gp3-qqp3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WeChat Pay Java SDK","requires_auth":"none","summary":"An attacker can exploit an XML External Entity vulnerability in the WeChat Pay Java SDK 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":"wechat_pay","vendor":"tencent"}],"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":"WXPayUtil in WeChat Pay Java SDK allows XXE attacks involving a merchant notification URL.","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":false,"headline":"WeChat Pay Java SDK allows XXE","id":"CVE-2018-13439","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xxe","year":"2018"},"n_packages":2,"n_references":1,"next":{"headline":"Null dereference in n/a","id":"CVE-2018-13440"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["3"],"package":"com.github.wxpay:wxpay-sdk","purl":null,"source":"GHSA-gqgv-2gp3-qqp3"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["3"],"package":"com.github.wxpay:wxpay-sdk","purl":"pkg:maven/com.github.wxpay/wxpay-sdk","source":"GHSA-gqgv-2gp3-qqp3"}],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2018-13435"},"products":["n/a"],"published":"2018-07-08","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":"2024-08-05","vendors":["n/a"]},"summary":"An attacker can exploit an XML External Entity vulnerability in the WeChat Pay Java SDK to read sensitive files or cause denial of service.","url":"https://insights.sbomify.com/CVE-2018-13439/"}
