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-2021-27116 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/beego/beego (Go): affected all versions; no fix listed\n- github.com/beego/beego (Go): affected all versions; no fix listed\n- github.com/beego/beego/v2 (Go): affected from 2.0.0; fixed in 2.0.2\n- github.com/beego/beego/v2 (Go): affected from 2.0.0; fixed in 2.0.2\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-2021-27116/ (Markdown: https://insights.sbomify.com/CVE-2021-27116/index.md)","id":"CVE-2021-27116","markdown":"https://insights.sbomify.com/CVE-2021-27116/index.md","name":"CVE-2021-27116","record":{"aliases":["GHSA-ffjp-66mx-3qpj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Go web framework","requires_auth":"low_privilege","summary":"Local attackers can exploit symlink vulnerabilities in the profiling module to read or modify arbitrary files.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"beego","vendor":"beego"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AC:L/AV:L/A:H/C:H/I:H/PR:L/S:U/UI:N","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"An issue was discovered in file profile.go in function MemProf in beego through 2.0.2, allows attackers to launch symlink attacks locally.","ecosystems":["Go"],"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":"Privilege escalation in beego","id":"CVE-2021-27116","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":4,"n_references":1,"next":{"headline":"Privilege escalation in beego","id":"CVE-2021-27117"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/beego/beego","purl":null,"source":"GHSA-ffjp-66mx-3qpj"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/beego/beego","purl":"pkg:golang/github.com/beego/beego","source":"GHSA-ffjp-66mx-3qpj"},{"ecosystem":"Go","fixed":["2.0.2"],"introduced":["2.0.0"],"last_affected":[],"package":"github.com/beego/beego/v2","purl":null,"source":"GHSA-ffjp-66mx-3qpj"},{"ecosystem":"Go","fixed":["2.0.2"],"introduced":["2.0.0"],"last_affected":[],"package":"github.com/beego/beego/v2","purl":"pkg:golang/github.com/beego/beego/v2","source":"GHSA-ffjp-66mx-3qpj"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-27114"},"products":["n/a"],"published":"2022-04-05","related":[{"cvss_score":9.8,"headline":"Path Traversal in Beego","id":"CVE-2022-31836","kev_date_added":null,"published":"2022-07-05"},{"cvss_score":9.8,"headline":"Access control bypass in beego","id":"CVE-2022-31259","kev_date_added":null,"published":"2022-05-21"},{"cvss_score":9.8,"headline":"Access control bypass in Beego","id":"CVE-2021-30080","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":9.3,"headline":"Beego allows Reflected/Stored XSS in Beego's RenderForm() Function Due to Unescaped User Input","id":"CVE-2025-30223","kev_date_added":null,"published":"2025-03-31"},{"cvss_score":8.8,"headline":"Beego privilege escalation vulnerability","id":"CVE-2024-40464","kev_date_added":null,"published":"2024-07-31"},{"cvss_score":8.8,"headline":"Beego privilege escalation vulnerability","id":"CVE-2024-40465","kev_date_added":null,"published":"2024-07-31"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"Local attackers can exploit symlink vulnerabilities in the profiling module to read or modify arbitrary files.","url":"https://insights.sbomify.com/CVE-2021-27116/"}
