An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-13883 in the wild and no public exploit code.\n\nAffected product: Wso2 Api Manager. 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-2020-13883/ (Markdown: https://insights.sbomify.com/CVE-2020-13883/index.md)","id":"CVE-2020-13883","markdown":"https://insights.sbomify.com/CVE-2020-13883/index.md","name":"CVE-2020-13883","record":{"aliases":["GHSA-m63m-4jjg-fw34"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WSO2 API Manager","requires_auth":"high_privilege","summary":"Attackers can exploit XML External Entity vulnerabilities in the Management Console to read sensitive data or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"api_manager","vendor":"wso2"},{"product":"api_microgateway","vendor":"wso2"},{"product":"identity_server_as_key_manager","vendor":"wso2"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AC:L/AV:N/A:H/C:L/I:N/PR:H/S:U/UI:N","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"In WSO2 API Manager 3.0.0 and earlier, WSO2 API Microgateway 2.2.0, and WSO2 IS as Key Manager 5.9.0 and earlier, Management Console allows XXE during addition or update of a Lifecycle.","ecosystems":[],"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":"XML external entity in n/a","id":"CVE-2020-13883","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wso2:api_manager","products":["wso2:api_manager","wso2:identity_server_as_key_manager"],"type":"xxe","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2020-13884"},"packages":[],"prev":{"headline":"Race condition in n/a","id":"CVE-2020-13882"},"products":["n/a"],"published":"2020-06-06","related":[{"cvss_score":9.8,"headline":"WSO2 Multiple Products Unrestrictive Upload of File","id":"CVE-2022-29464","kev_date_added":"2022-04-25","published":"2022-04-18"},{"cvss_score":9.8,"headline":"Incorrect Authorization in Multiple WSO2 Products via Account Recovery SOAP Admin Service Leading to Account Takeover","id":"CVE-2024-6914","kev_date_added":null,"published":"2025-05-22"},{"cvss_score":9.8,"headline":"WSO2 API Manager vulnerable to SSRF","id":"CVE-2020-13226","kev_date_added":null,"published":"2020-05-20"},{"cvss_score":9.1,"headline":"An XML External Entity (XXE) vulnerability in Multiple WSO2 Products","id":"CVE-2025-2905","kev_date_added":null,"published":"2025-05-05"},{"cvss_score":9.1,"headline":"XML external entity in n/a","id":"CVE-2021-42646","kev_date_added":null,"published":"2022-05-11"},{"cvss_score":9.1,"headline":"XML external entity in n/a","id":"CVE-2020-24589","kev_date_added":null,"published":"2020-08-21"},{"cvss_score":9.1,"headline":"XML external entity in n/a","id":"CVE-2020-24590","kev_date_added":null,"published":"2020-08-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can exploit XML External Entity vulnerabilities in the Management Console to read sensitive data or cause denial of service.","url":"https://insights.sbomify.com/CVE-2020-13883/"}
