An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-21517 in the wild and no public exploit code.\n\nAffected product: Metinfo Metinfo. 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-2020-21517/ (Markdown: https://insights.sbomify.com/CVE-2020-21517/index.md)","id":"CVE-2020-21517","markdown":"https://insights.sbomify.com/CVE-2020-21517/index.md","name":"CVE-2020-21517","record":{"aliases":["GHSA-mv7p-c3fc-fvrx"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MetInfo CMS","requires_auth":"none","summary":"An attacker can inject malicious scripts via the gourl parameter in login.php, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"metinfo","vendor":"metinfo"}],"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":"Cross Site Scripting (XSS) vulnerability in MetInfo 7.0.0 via the gourl parameter in login.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":null,"headline":"Cross-site scripting in n/a","id":"CVE-2020-21517","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"metinfo:metinfo","products":["metinfo:metinfo"],"type":"xss","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-2020-21522"},"packages":[],"prev":{"headline":"FeehiCMS has an arbitrary file upload vulnerability","id":"CVE-2020-21516"},"products":["n/a"],"published":"2021-06-21","related":[{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2022-22295","kev_date_added":null,"published":"2022-02-14"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2022-23335","kev_date_added":null,"published":"2022-02-14"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2020-21127","kev_date_added":null,"published":"2021-09-15"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2020-19305","kev_date_added":null,"published":"2021-08-03"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2020-18175","kev_date_added":null,"published":"2021-07-29"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2020-21132","kev_date_added":null,"published":"2021-07-12"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2020-21133","kev_date_added":null,"published":"2021-07-12"}],"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":"2026-07-09","vendors":["n/a"]},"summary":"An attacker can inject malicious scripts via the gourl parameter in login.php, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2020-21517/"}
