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-2020-27408 in the wild and no public exploit code.\n\nAffected product: Os4ed Opensis. 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-2020-27408/ (Markdown: https://insights.sbomify.com/CVE-2020-27408/index.md)","id":"CVE-2020-27408","markdown":"https://insights.sbomify.com/CVE-2020-27408/index.md","name":"CVE-2020-27408","record":{"aliases":["GHSA-rg77-jjpv-33p3"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSIS Community Edition","requires_auth":"none","summary":"Unauthenticated attackers can change arbitrary user passwords via incorrect access controls in ResetUserInfo.php, leading to account takeover.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"opensis","vendor":"os4ed"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-640","name":"Weak Password Recovery Mechanism for Forgotten Password"},{"id":"CWE-287","name":"Improper Authentication"}],"description":"OpenSIS Community Edition through 7.6 is affected by incorrect access controls for the file ResetUserInfo.php that allow an unauthenticated attacker to change the password of arbitrary users.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Auth bypass in n/a","id":"CVE-2020-27408","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"os4ed:opensis","products":["os4ed:opensis"],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-27409"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-27406"},"products":["n/a"],"published":"2020-12-04","related":[{"cvss_score":10,"headline":"Code injection in OS4Ed","id":"CVE-2020-6143","kev_date_added":null,"published":"2020-09-01"},{"cvss_score":10,"headline":"Code injection in OS4Ed","id":"CVE-2020-6144","kev_date_added":null,"published":"2020-09-01"},{"cvss_score":9.9,"headline":"Path traversal in OS4Ed","id":"CVE-2020-6142","kev_date_added":null,"published":"2020-09-01"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2021-41691","kev_date_added":null,"published":"2025-06-24"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2025-22926","kev_date_added":null,"published":"2025-04-03"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2025-22928","kev_date_added":null,"published":"2025-04-03"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2025-22929","kev_date_added":null,"published":"2025-04-03"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Unauthenticated attackers can change arbitrary user passwords via incorrect access controls in ResetUserInfo.php, leading to account takeover.","url":"https://insights.sbomify.com/CVE-2020-27408/"}
