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-2009-4109 in the wild and no public exploit code.\n\nAffected product: Dnnsoftware Dotnetnuke. 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-2009-4109/ (Markdown: https://insights.sbomify.com/CVE-2009-4109/index.md)","id":"CVE-2009-4109","markdown":"https://insights.sbomify.com/CVE-2009-4109/index.md","name":"CVE-2009-4109","record":{"aliases":["GHSA-vc99-gqjv-x726"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"DotNetNuke CMS","requires_auth":"none","summary":"Remote attackers can access sensitive version information via the install wizard without authentication, exposing DotNetNuke CMS instances to reconnaissance.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dotnetnuke","vendor":"dnnsoftware"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:N/A:N","version":"2.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The install wizard in DotNetNuke 4.0 through 5.1.4 does not prevent anonymous users from accessing functionality related to determination of the need for an upgrade, which allows remote attackers to access version information and possibly other sensitive information.","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":"Information disclosure in n/a","id":"CVE-2009-4109","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dnnsoftware:dotnetnuke","products":["dnnsoftware:dotnetnuke"],"type":"information_disclosure","year":"2009"},"n_packages":0,"n_references":4,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2009-4110"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2009-4108"},"products":["n/a"],"published":"2009-11-28","related":[{"cvss_score":8.8,"headline":"DotNetNuke (DNN) Remote Code Execution","id":"CVE-2017-9822","kev_date_added":"2021-11-03","published":"2017-07-20"},{"cvss_score":7.5,"headline":"DotNetNuke (DNN) Inadequate Encryption Strength","id":"CVE-2018-15811","kev_date_added":"2021-11-03","published":"2019-07-03"},{"cvss_score":7.5,"headline":"DotNetNuke (DNN) Inadequate Encryption Strength","id":"CVE-2018-18325","kev_date_added":"2021-11-03","published":"2019-07-03"},{"cvss_score":10,"headline":"DNN Insufficient Access Control - Image Upload allows for Site Content Overwrite","id":"CVE-2025-64095","kev_date_added":null,"published":"2025-10-28"},{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2006-3601","kev_date_added":null,"published":"2006-07-14"},{"cvss_score":9.8,"headline":"The installation wizard in DotNetNuke (DNN) allows privilege escalation","id":"CVE-2015-2794","kev_date_added":null,"published":"2017-02-06"},{"cvss_score":9.1,"headline":"DotNetNuke.Core Vulnerable to Stored XSS via Module Title","id":"CVE-2026-24838","kev_date_added":null,"published":"2026-01-27"}],"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":"2024-09-16","vendors":["n/a"]},"summary":"Remote attackers can access sensitive version information via the install wizard without authentication, exposing DotNetNuke CMS instances to reconnaissance.","url":"https://insights.sbomify.com/CVE-2009-4109/"}
