Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-38156 exists.\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-2021-38156/ (Markdown: https://insights.sbomify.com/CVE-2021-38156/index.md)","id":"CVE-2021-38156","markdown":"https://insights.sbomify.com/CVE-2021-38156/index.md","name":"CVE-2021-38156","record":{"aliases":["GHSA-2cr4-q4vr-2q6r"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Nagios XI monitoring","requires_auth":"low_privilege","summary":"Cross-site scripting in Nagios XI dashboard editing allows attackers to execute scripts in admin sessions, potentially leading to account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nagios_xi","vendor":"nagios"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In Nagios XI before 5.8.6, XSS exists in the dashboard page (/dashboards/#) when administrative users attempt to edit a dashboard.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2021/CVE-2021-38156.yaml","stars":null,"title":"Nagios XI \u003c 5.8.6 - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2021-38156","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"nagios:nagios_xi","products":["nagios:nagios_xi"],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-38157"},"packages":[],"prev":{"headline":"OpenStack Keystone allows information disclosure during account locking","id":"CVE-2021-38155"},"products":["n/a"],"published":"2021-09-15","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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Cross-site scripting in Nagios XI dashboard editing allows attackers to execute scripts in admin sessions, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2021-38156/"}
