An attacker can exploit it over the internet without logging in, 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-2021-26247 exists.\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-2021-26247/ (Markdown: https://insights.sbomify.com/CVE-2021-26247/index.md)","id":"CVE-2021-26247","markdown":"https://insights.sbomify.com/CVE-2021-26247/index.md","name":"CVE-2021-26247","record":{"aliases":["DEBIAN-CVE-2021-26247","GHSA-cvpj-w72w-rchg","UBUNTU-CVE-2021-26247"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Cacti monitoring tool","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary JavaScript via the ref parameter in the password change page, potentially leading to session hijacking or malicious actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"cacti","vendor":"cacti"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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":"As an unauthenticated remote user, visit \"http://\u003cCACTI_SERVER\u003e/auth_changepassword.php?ref=\u003cscript\u003ealert(1)\u003c/script\u003e\" to successfully execute the JavaScript payload present in the \"ref\" URL parameter.","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-2021-26247.yaml","stars":null,"title":"Cacti - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":true,"headline":"Cross-site scripting in Cacti","id":"CVE-2021-26247","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":"Philips MRI 1.5T and 3T Incorrect Ownership Assignment","id":"CVE-2021-26248"},"packages":[],"prev":{"headline":"This candidate was in a CNA pool that was not assigned to any issues during 2021.","id":"CVE-2021-26246"},"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Unauthenticated attackers can execute arbitrary JavaScript via the ref parameter in the password change page, potentially leading to session hijacking or malicious actions.","url":"https://insights.sbomify.com/CVE-2021-26247/"}
