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-2021-29047 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.liferay.portal:release.dxp.bom (Maven): affected all versions; fixed in 7.3.10.fp1\n- com.liferay.portal:release.dxp.bom (Maven): affected all versions; fixed in 7.3.10.fp1\n- com.liferay.portal:release.portal.bom (Maven): affected from 7.3.4; fixed in 7.3.6\n- com.liferay.portal:release.portal.bom (Maven): affected from 7.3.4; fixed in 7.3.6\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-2021-29047/ (Markdown: https://insights.sbomify.com/CVE-2021-29047/index.md)","id":"CVE-2021-29047","markdown":"https://insights.sbomify.com/CVE-2021-29047/index.md","name":"CVE-2021-29047","record":{"aliases":["GHSA-9mxg-p873-6793"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Liferay Portal","requires_auth":"none","summary":"Attackers can bypass CAPTCHA protection in Liferay Portal by reusing valid answers, allowing repeated execution of protected actions.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dxp","vendor":"liferay"},{"product":"liferay_portal","vendor":"liferay"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The SimpleCaptcha implementation in Liferay Portal 7.3.4, 7.3.5 and Liferay DXP 7.3 before fix pack 1 does not invalidate CAPTCHA answers after it is used, which allows remote attackers to repeatedly perform actions protected by a CAPTCHA challenge by reusing the same CAPTCHA answer.","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":"Liferay Portal and Liferay DXP Fails to Invalidate CAPTCHA Answers After Use","id":"CVE-2021-29047","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"liferay:liferay_portal","products":["liferay:liferay_portal"],"type":"security_feature_bypass","year":"2021"},"n_packages":4,"n_references":1,"next":{"headline":"Liferay Portal and Liferay DXP Vulnerable to Cross-Site Scripting (XSS) in the Layout Admin Page","id":"CVE-2021-29048"},"packages":[{"ecosystem":"Maven","fixed":["7.3.10.fp1"],"introduced":["0"],"last_affected":[],"package":"com.liferay.portal:release.dxp.bom","purl":null,"source":"GHSA-9mxg-p873-6793"},{"ecosystem":"Maven","fixed":["7.3.10.fp1"],"introduced":["0"],"last_affected":[],"package":"com.liferay.portal:release.dxp.bom","purl":"pkg:maven/com.liferay.portal/release.dxp.bom","source":"GHSA-9mxg-p873-6793"},{"ecosystem":"Maven","fixed":["7.3.6"],"introduced":["7.3.4"],"last_affected":[],"package":"com.liferay.portal:release.portal.bom","purl":null,"source":"GHSA-9mxg-p873-6793"},{"ecosystem":"Maven","fixed":["7.3.6"],"introduced":["7.3.4"],"last_affected":[],"package":"com.liferay.portal:release.portal.bom","purl":"pkg:maven/com.liferay.portal/release.portal.bom","source":"GHSA-9mxg-p873-6793"}],"prev":{"headline":"Liferay Portal and Liferay DXP Vulnerable to Cross-Site Scripting (XSS) via Asset Module Parameter","id":"CVE-2021-29046"},"products":["n/a"],"published":"2021-05-16","related":[{"cvss_score":9.8,"headline":"Liferay Portal and Liferay DXP Vulnerable to SQL Injection via the Fragment Module","id":"CVE-2022-42120","kev_date_added":null,"published":"2022-11-15"},{"cvss_score":9.8,"headline":"Liferay Portal and Liferay DXP Vulnerable to SQL Injection via Friendly URL Module","id":"CVE-2022-42122","kev_date_added":null,"published":"2022-11-15"},{"cvss_score":8.8,"headline":"Liferay Portal and Liferay DXP Vulnerable to CSRF via the Layout Module","id":"CVE-2023-35030","kev_date_added":null,"published":"2023-06-15"},{"cvss_score":8.8,"headline":"Liferay Portal and Liferay DXP Vulnerable to Multiple SQL Injections","id":"CVE-2021-29053","kev_date_added":null,"published":"2021-05-17"},{"cvss_score":7.5,"headline":"Liferay Portal and Liferay DXP insecure default configuration","id":"CVE-2021-33321","kev_date_added":null,"published":"2021-08-03"},{"cvss_score":6.5,"headline":"Liferay Portal and Liferay DXP Fails to Check Permissions in Translation Module","id":"CVE-2022-38512","kev_date_added":null,"published":"2022-09-22"}],"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":"2026-07-09","vendors":["n/a"]},"summary":"Attackers can bypass CAPTCHA protection in Liferay Portal by reusing valid answers, allowing repeated execution of protected actions.","url":"https://insights.sbomify.com/CVE-2021-29047/"}
