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-2020-13485 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- verbb/knock-knock (Packagist): affected all versions; fixed in 1.2.8\n- verbb/knock-knock (Packagist): affected all versions; fixed in 1.2.8\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-2020-13485/ (Markdown: https://insights.sbomify.com/CVE-2020-13485/index.md)","id":"CVE-2020-13485","markdown":"https://insights.sbomify.com/CVE-2020-13485/index.md","name":"CVE-2020-13485","record":{"aliases":["GHSA-wxvr-qqm7-6h65"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Craft CMS plugin","requires_auth":"none","summary":"Attackers can bypass IP whitelist restrictions in the Knock Knock plugin for Craft CMS by spoofing the X-Forwarded-For header.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"knock_knock","vendor":"verbb"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-697","name":"Incorrect Comparison"}],"description":"The Knock Knock plugin before 1.2.8 for Craft CMS allows IP Whitelist bypass via an X-Forwarded-For HTTP header.","ecosystems":["Packagist"],"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":"Knock Knock plugin IP Whitelist bypass via an X-Forwarded-For HTTP header","id":"CVE-2020-13485","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"security_feature_bypass","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Knock Knock plugin Open redirection vulnerability","id":"CVE-2020-13486"},"packages":[{"ecosystem":"Packagist","fixed":["1.2.8"],"introduced":["0"],"last_affected":[],"package":"verbb/knock-knock","purl":null,"source":"GHSA-wxvr-qqm7-6h65"},{"ecosystem":"Packagist","fixed":["1.2.8"],"introduced":["0"],"last_affected":[],"package":"verbb/knock-knock","purl":"pkg:composer/verbb/knock-knock","source":"GHSA-wxvr-qqm7-6h65"}],"prev":{"headline":"Server-side request forgery in n/a","id":"CVE-2020-13484"},"products":["n/a"],"published":"2020-05-25","related":[{"cvss_score":6.1,"headline":"Knock Knock plugin Open redirection vulnerability","id":"CVE-2020-13486","kev_date_added":null,"published":"2020-05-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"Attackers can bypass IP whitelist restrictions in the Knock Knock plugin for Craft CMS by spoofing the X-Forwarded-For header.","url":"https://insights.sbomify.com/CVE-2020-13485/"}
