Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-5186 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- DotNetNuke.Core (NuGet): affected all versions up to 9.4.4; no fix listed\n- DotNetNuke.Core (NuGet): affected all versions up to 9.4.4; no fix listed\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-2020-5186/ (Markdown: https://insights.sbomify.com/CVE-2020-5186/index.md)","id":"CVE-2020-5186","markdown":"https://insights.sbomify.com/CVE-2020-5186/index.md","name":"CVE-2020-5186","record":{"aliases":["GHSA-9phr-h5mx-4fp6"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"DNN CMS","requires_auth":"low_privilege","summary":"Cross-site scripting vulnerability in DNN allows attackers to inject malicious scripts, 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":"dotnetnuke","vendor":"dnnsoftware"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"DNN (formerly DotNetNuke) through 9.4.4 allows XSS (issue 1 of 2).","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"DNN XSS Vulnerability","id":"CVE-2020-5186","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":"dnnsoftware:dotnetnuke","products":["dnnsoftware:dotnetnuke"],"type":"xss","year":"2020"},"n_packages":2,"n_references":3,"next":{"headline":"DNN Path Traversal via Zip Slip","id":"CVE-2020-5187"},"packages":[{"ecosystem":"NuGet","fixed":[],"introduced":["0"],"last_affected":["9.4.4"],"package":"DotNetNuke.Core","purl":null,"source":"GHSA-9phr-h5mx-4fp6"},{"ecosystem":"NuGet","fixed":[],"introduced":["0"],"last_affected":["9.4.4"],"package":"DotNetNuke.Core","purl":"pkg:nuget/DotNetNuke.Core","source":"GHSA-9phr-h5mx-4fp6"}],"prev":{"headline":"Null dereference in n/a","id":"CVE-2020-5183"},"products":["n/a"],"published":"2020-02-24","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":"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":"Cross-site scripting vulnerability in DNN allows attackers to inject malicious scripts, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2020-5186/"}
