Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-20023 in the wild and no public exploit code.\n\nAffected product: CKSource CKFinder. 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-2016-20023/ (Markdown: https://insights.sbomify.com/CVE-2016-20023/index.md)","id":"CVE-2016-20023","markdown":"https://insights.sbomify.com/CVE-2016-20023/index.md","name":"CVE-2016-20023","record":{"aliases":["GHSA-fv5g-wf76-67g3"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"CKFinder file manager","requires_auth":"low_privilege","summary":"Authenticated attackers can download arbitrary server files by providing correct paths in CKFinder for ASP.NET.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ckfinder","vendor":"cksource"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"In CKSource CKFinder before 2.5.0.1 for ASP.NET, authenticated users could download any file from the server if the correct path to a file was provided.","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":"Path traversal in CKFinder","id":"CVE-2016-20023","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2016"},"n_packages":0,"n_references":1,"next":{"headline":"ZKTeco ZKTime.Net 3.0.1.6 Insecure File Permissions Privilege Escalation","id":"CVE-2016-20024"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2016-20022"},"products":["CKFinder"],"published":"2025-12-05","related":[{"cvss_score":7.5,"headline":"File upload in n/a","id":"CVE-2019-15862","kev_date_added":null,"published":"2019-09-26"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2025-63830","kev_date_added":null,"published":"2025-11-14"},{"cvss_score":5.3,"headline":"Information disclosure in n/a","id":"CVE-2019-15891","kev_date_added":null,"published":"2019-09-26"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-12-05","vendors":["CKSource"]},"summary":"Authenticated attackers can download arbitrary server files by providing correct paths in CKFinder for ASP.NET.","url":"https://insights.sbomify.com/CVE-2016-20023/"}
