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-2021-37421 in the wild and no public exploit code.\n\nAffected product: Zohocorp Manageengine Adselfservice Plus. 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-2021-37421/ (Markdown: https://insights.sbomify.com/CVE-2021-37421/index.md)","id":"CVE-2021-37421","markdown":"https://insights.sbomify.com/CVE-2021-37421/index.md","name":"CVE-2021-37421","record":{"aliases":["GHSA-ph4j-7hhh-88v8"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"AD Self-Service Portal","requires_auth":"none","summary":"Attackers can bypass admin portal access restrictions in Zoho ManageEngine ADSelfService Plus to gain unauthorized administrative privileges.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"manageengine_adselfservice_plus","vendor":"zohocorp"}],"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-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Zoho ManageEngine ADSelfService Plus 6103 and prior is vulnerable to admin portal access-restriction bypass.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Auth bypass in n/a","id":"CVE-2021-37421","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"zohocorp:manageengine_adselfservice_plus","products":["zohocorp:manageengine_adselfservice_plus"],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection in n/a","id":"CVE-2021-37422"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2021-37420"},"products":["n/a"],"published":"2021-08-30","related":[{"cvss_score":9.8,"headline":"Zoho ManageEngine ADSelfService Plus Authentication Bypass","id":"CVE-2021-40539","kev_date_added":"2021-11-03","published":"2021-09-07"},{"cvss_score":6.8,"headline":"Zoho ManageEngine ADSelfService Plus Remote Code Execution","id":"CVE-2022-28810","kev_date_added":"2023-03-07","published":"2022-04-18"},{"cvss_score":10,"headline":"Server-side request forgery in n/a","id":"CVE-2019-3905","kev_date_added":null,"published":"2019-01-03"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2023-35854","kev_date_added":null,"published":"2023-06-20"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2021-37422","kev_date_added":null,"published":"2021-09-10"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2021-37423","kev_date_added":null,"published":"2021-09-10"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-33055","kev_date_added":null,"published":"2021-08-30"}],"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 bypass admin portal access restrictions in Zoho ManageEngine ADSelfService Plus to gain unauthorized administrative privileges.","url":"https://insights.sbomify.com/CVE-2021-37421/"}
