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-2019-16891 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.liferay.portal:release.portal.bom (Maven): affected all versions; fixed in 7.1.1\n- com.liferay.portal:release.portal.bom (Maven): affected all versions; fixed in 7.1.1\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-2019-16891/ (Markdown: https://insights.sbomify.com/CVE-2019-16891/index.md)","id":"CVE-2019-16891","markdown":"https://insights.sbomify.com/CVE-2019-16891/index.md","name":"CVE-2019-16891","record":{"aliases":["CVE-2022-44147","GHSA-372h-p48h-xw8q"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Liferay Portal","requires_auth":"none","summary":"Remote attackers can execute arbitrary commands on Liferay Portal CE by sending a malicious JSON payload that triggers unsafe deserialization.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"liferay_portal","vendor":"liferay"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Liferay Portal CE 6.2.5 allows remote command execution because of deserialization of a JSON payload.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2025-05-06","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-05-06T04:05:41Z","kind":"github_poc","ref":"https://github.com/rai0ffs3c/CVE-2019-16891-Liferay-deserialization-RCE","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Liferay Portal Allows RCE via Deserialization of a JSON Payload","id":"CVE-2019-16891","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"liferay:liferay_portal","products":["liferay:liferay_portal"],"type":"deserialization","year":"2019"},"n_packages":2,"n_references":4,"next":{"headline":"Rubyzip denial of service","id":"CVE-2019-16892"},"packages":[{"ecosystem":"Maven","fixed":["7.1.1"],"introduced":["0"],"last_affected":[],"package":"com.liferay.portal:release.portal.bom","purl":null,"source":"GHSA-372h-p48h-xw8q"},{"ecosystem":"Maven","fixed":["7.1.1"],"introduced":["0"],"last_affected":[],"package":"com.liferay.portal:release.portal.bom","purl":"pkg:maven/com.liferay.portal/release.portal.bom","source":"GHSA-372h-p48h-xw8q"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2019-16890"},"products":["n/a"],"published":"2019-10-04","related":[{"cvss_score":9.8,"headline":"Liferay Portal Deserialization of Untrusted Data","id":"CVE-2020-7961","kev_date_added":"2021-11-03","published":"2020-03-20"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2021-33990","kev_date_added":null,"published":"2023-04-16"},{"cvss_score":9.6,"headline":"Liferay Portal XSS with `p_l_back_url_title` on edit content page","id":"CVE-2023-47797","kev_date_added":null,"published":"2023-11-17"},{"cvss_score":8.8,"headline":"Liferay Portal and Liferay DXP Vulnerable to Arbitrary Code Execution","id":"CVE-2020-13445","kev_date_added":null,"published":"2020-06-10"},{"cvss_score":8.8,"headline":"File upload in n/a","id":"CVE-2018-10795","kev_date_added":null,"published":"2018-05-07"},{"cvss_score":8.8,"headline":"Shell command injection in Liferay Portal","id":"CVE-2010-5327","kev_date_added":null,"published":"2017-01-13"}],"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)"},{"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":"Remote attackers can execute arbitrary commands on Liferay Portal CE by sending a malicious JSON payload that triggers unsafe deserialization.","url":"https://insights.sbomify.com/CVE-2019-16891/"}
