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-2021-28411 exists.\n\nAffected product: Ruoyi Ruoyi. 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-2021-28411/ (Markdown: https://insights.sbomify.com/CVE-2021-28411/index.md)","id":"CVE-2021-28411","markdown":"https://insights.sbomify.com/CVE-2021-28411/index.md","name":"CVE-2021-28411","record":{"aliases":["GHSA-gmjc-pqvw-6h79"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"RuoYi admin framework","requires_auth":"none","summary":"Remote attackers can escalate privileges via unsafe deserialization in the remember-me cookie handling of the RuoYi framework.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ruoyi","vendor":"ruoyi"}],"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-269","name":"Improper Privilege Management"}],"description":"An issue was discovered in getRememberedSerializedIdentity function in CookieRememberMeManager class in lerry903 RuoYi version 3.4.0, allows remote attackers to escalate privileges.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Deserialization in n/a","id":"CVE-2021-28411","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ruoyi:ruoyi","products":["ruoyi:ruoyi"],"type":"deserialization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-28417"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-28399"},"products":["n/a"],"published":"2023-08-11","related":[{"cvss_score":10,"headline":"SQL injection in n/a","id":"CVE-2024-57521","kev_date_added":null,"published":"2025-12-23"},{"cvss_score":9.8,"headline":"Privilege escalation in n/a","id":"CVE-2025-28402","kev_date_added":null,"published":"2025-04-07"},{"cvss_score":9.8,"headline":"Privilege escalation in n/a","id":"CVE-2025-28405","kev_date_added":null,"published":"2025-04-07"},{"cvss_score":9.8,"headline":"Privilege escalation in n/a","id":"CVE-2025-28406","kev_date_added":null,"published":"2025-04-07"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2025-28408","kev_date_added":null,"published":"2025-04-07"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2025-28410","kev_date_added":null,"published":"2025-04-07"},{"cvss_score":9.8,"headline":"Privilege escalation in n/a","id":"CVE-2025-28411","kev_date_added":null,"published":"2025-04-07"}],"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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-10-09","vendors":["n/a"]},"summary":"Remote attackers can escalate privileges via unsafe deserialization in the remember-me cookie handling of the RuoYi framework.","url":"https://insights.sbomify.com/CVE-2021-28411/"}
