An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-3287 exists.\n\nAffected product: Zohocorp Manageengine Opmanager. 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-2021-3287/ (Markdown: https://insights.sbomify.com/CVE-2021-3287/index.md)","id":"CVE-2021-3287","markdown":"https://insights.sbomify.com/CVE-2021-3287/index.md","name":"CVE-2021-3287","record":{"aliases":["GHSA-9342-c88m-74xw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Network monitoring software","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary code on Zoho ManageEngine OpManager servers due to a deserialization bypass.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"manageengine_opmanager","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-502","name":"Deserialization of Untrusted Data"}],"description":"Zoho ManageEngine OpManager before 12.5.329 allows unauthenticated Remote Code Execution due to a general bypass in the deserialization class.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-07-26","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":1,"refs":[{"date":"2021-07-26","kind":"metasploit","ref":"exploit/multi/http/opmanager_sumpdu_deserialization","stars":null,"title":"ManageEngine OpManager SumPDU Java Deserialization"},{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-3287.yaml","stars":null,"title":"Zoho ManageEngine OpManager \u003c 12.5.329 - Remote Code Execution"}],"tier":"weaponised"},"has_fix":null,"headline":"Deserialization in n/a","id":"CVE-2021-3287","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"zohocorp:manageengine_opmanager","products":["zohocorp:manageengine_opmanager"],"type":"deserialization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Zen Cart vulnerable to authenticated remote code execution","id":"CVE-2021-3291"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2021-3286"},"products":["n/a"],"published":"2021-04-22","related":[{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2022-29535","kev_date_added":null,"published":"2022-05-05"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2021-44514","kev_date_added":null,"published":"2021-12-09"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2021-40493","kev_date_added":null,"published":"2021-10-13"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2021-41075","kev_date_added":null,"published":"2021-10-13"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2021-41288","kev_date_added":null,"published":"2021-09-30"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2020-28653","kev_date_added":null,"published":"2021-02-03"}],"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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Unauthenticated attackers can execute arbitrary code on Zoho ManageEngine OpManager servers due to a deserialization bypass.","url":"https://insights.sbomify.com/CVE-2021-3287/"}
