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-2021-37351 in the wild and no public exploit code.\n\nAffected product: Nagios Nagios Xi. 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-2021-37351/ (Markdown: https://insights.sbomify.com/CVE-2021-37351/index.md)","id":"CVE-2021-37351","markdown":"https://insights.sbomify.com/CVE-2021-37351/index.md","name":"CVE-2021-37351","record":{"aliases":["GHSA-837c-9cp4-5j9q"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Nagios XI monitoring","requires_auth":"none","summary":"Unauthenticated attackers can access guarded pages in Nagios XI via crafted HTTP requests due to insecure permissions.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nagios_xi","vendor":"nagios"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"Nagios XI before version 5.8.5 is vulnerable to insecure permissions and allows unauthenticated users to access guarded pages through a crafted HTTP request to the 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":"Auth bypass in n/a","id":"CVE-2021-37351","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"nagios:nagios_xi","products":["nagios:nagios_xi"],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Open redirect in n/a","id":"CVE-2021-37352"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2021-37350"},"products":["n/a"],"published":"2021-08-13","related":[{"cvss_score":8.8,"headline":"Nagios XI OS Command Injection","id":"CVE-2021-25296","kev_date_added":"2022-01-18","published":"2021-02-15"},{"cvss_score":8.8,"headline":"Nagios XI OS Command Injection","id":"CVE-2021-25297","kev_date_added":"2022-01-18","published":"2021-02-15"},{"cvss_score":8.8,"headline":"Nagios XI OS Command Injection","id":"CVE-2021-25298","kev_date_added":"2022-01-18","published":"2021-02-15"},{"cvss_score":8.8,"headline":"Nagios XI Remote Code Execution","id":"CVE-2019-15949","kev_date_added":"2021-11-03","published":"2019-09-05"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2024-24401","kev_date_added":null,"published":"2024-02-26"},{"cvss_score":9.8,"headline":"Privilege escalation in n/a","id":"CVE-2024-24402","kev_date_added":null,"published":"2024-02-26"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2023-48084","kev_date_added":null,"published":"2023-12-14"}],"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 access guarded pages in Nagios XI via crafted HTTP requests due to insecure permissions.","url":"https://insights.sbomify.com/CVE-2021-37351/"}
