Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-3816 in the wild and no public exploit code.\n\nAffected product: Cacti Cacti. 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-2021-3816/ (Markdown: https://insights.sbomify.com/CVE-2021-3816/index.md)","id":"CVE-2021-3816","markdown":"https://insights.sbomify.com/CVE-2021-3816/index.md","name":"CVE-2021-3816","record":{"aliases":["DEBIAN-CVE-2021-3816","GHSA-6gq5-766m-4c86","UBUNTU-CVE-2021-3816"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Network monitoring tool","requires_auth":"low_privilege","summary":"Authenticated users with User Management permissions can inject arbitrary HTML into group settings, potentially leading to session hijacking or malicious script execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"cacti","vendor":"cacti"}],"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":"Cacti 1.1.38 allows authenticated users with User Management permissions to inject arbitrary HTML in the group_prefix field during the creation of a new group via \"Copy\" method at user_group_admin.php.","ecosystems":[],"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":"Cross-site scripting in Cacti","id":"CVE-2021-3816","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cacti:cacti","products":["cacti:cacti"],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"SQL Injection in wbce/wbce_cms","id":"CVE-2021-3817"},"packages":[],"prev":{"headline":"Prototype Pollution in fabiocaccamo/utils.js","id":"CVE-2021-3815"},"products":["Cacti"],"published":"2022-01-19","related":[{"cvss_score":9.8,"headline":"Cacti Command Injection","id":"CVE-2022-46169","kev_date_added":"2023-02-16","published":"2022-12-05"},{"cvss_score":9.8,"headline":"Cacti: Pre-authentication SQL injection via rfilter RLIKE clause in graph_view.php","id":"CVE-2026-39893","kev_date_added":null,"published":"2026-06-24"},{"cvss_score":9.8,"headline":"Cacti: Unauthenticated RCE on Graph Image","id":"CVE-2026-39938","kev_date_added":null,"published":"2026-06-24"},{"cvss_score":9.8,"headline":"Cacti has Pre-Authentication SQL Injection via unanchored FILTER_VALIDATE_REGEXP in graph_view.php","id":"CVE-2026-39955","kev_date_added":null,"published":"2026-06-24"},{"cvss_score":9.8,"headline":"Unauthenticated SQL Injection in graph_view.php in Cacti","id":"CVE-2023-39361","kev_date_added":null,"published":"2023-09-05"},{"cvss_score":9.8,"headline":"Auth bypass in Cati","id":"CVE-2022-0730","kev_date_added":null,"published":"2022-03-03"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2017-12065","kev_date_added":null,"published":"2017-08-01"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"Authenticated users with User Management permissions can inject arbitrary HTML into group settings, potentially leading to session hijacking or malicious script execution.","url":"https://insights.sbomify.com/CVE-2021-3816/"}
