It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-23895 in the wild and no public exploit code.\n\nAffected product: McAfee,LLC McAfee Database Security (DBSec). 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-2021-23895/ (Markdown: https://insights.sbomify.com/CVE-2021-23895/index.md)","id":"CVE-2021-23895","markdown":"https://insights.sbomify.com/CVE-2021-23895/index.md","name":"CVE-2021-23895","record":{"aliases":["GHSA-f54c-rr24-8cqx"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Database Security Server","requires_auth":"low_privilege","summary":"Remote authenticated attackers can execute arbitrary code with administrator privileges via malicious Java serialized objects in McAfee DBSec.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"database_security","vendor":"mcafee"}],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of untrusted data vulnerability in McAfee Database Security (DBSec) prior to 4.8.2 allows a remote authenticated attacker to create a reverse shell with administrator privileges on the DBSec server via carefully constructed Java serialized object sent to the DBSec server.","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":"Authorized deserialization of untrusted data in McAfee DBSec","id":"CVE-2021-23895","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cleartext Transmission of Sensitive Information in McAfee DBSec","id":"CVE-2021-23896"},"packages":[],"prev":{"headline":"Unauthorized deserialization of untrusted data in McAfee DBSec","id":"CVE-2021-23894"},"products":["McAfee Database Security (DBSec)"],"published":"2021-06-02","related":[{"cvss_score":9.6,"headline":"Unauthorized deserialization of untrusted data in McAfee DBSec","id":"CVE-2021-23894","kev_date_added":null,"published":"2021-06-02"},{"cvss_score":6.3,"headline":"Database Security(DBS)-Use of a Broken or Risky Cryptographic Algorithm","id":"CVE-2020-7339","kev_date_added":null,"published":"2020-12-09"},{"cvss_score":6.1,"headline":"Denial of Service in Database Security on Windows","id":"CVE-2021-31850","kev_date_added":null,"published":"2021-12-08"},{"cvss_score":5.9,"headline":"Cross site Scripting (XSS) vulnerability in McAfee DBSec","id":"CVE-2021-31830","kev_date_added":null,"published":"2021-06-03"},{"cvss_score":5.3,"headline":"Data Leakage Vulnerability in McAfee Database Security web interface","id":"CVE-2019-3615","kev_date_added":null,"published":"2019-03-12"},{"cvss_score":4.9,"headline":"Incorrect access to deleted scripts vulnerability in McAfee DBSec","id":"CVE-2021-31831","kev_date_added":null,"published":"2021-06-03"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["McAfee,LLC"]},"summary":"Remote authenticated attackers can execute arbitrary code with administrator privileges via malicious Java serialized objects in McAfee DBSec.","url":"https://insights.sbomify.com/CVE-2021-23895/"}
