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-2021-31858 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-2021-31858/ (Markdown: https://insights.sbomify.com/CVE-2021-31858/index.md)","id":"CVE-2021-31858","markdown":"https://insights.sbomify.com/CVE-2021-31858/index.md","name":"CVE-2021-31858","record":{"aliases":["GHSA-3xxp-73wf-27cp"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"DotNetNuke CMS","requires_auth":"low_privilege","summary":"Authenticated users can inject arbitrary scripts into profile biographies, potentially leading to session hijacking or malicious actions on behalf of other users.","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":"DotNetNuke (DNN) 9.9.1 CMS is vulnerable to a Stored Cross-Site Scripting vulnerability in the user profile biography section which allows remote authenticated users to inject arbitrary code via a crafted payload.","ecosystems":[],"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":"Cross-site scripting in n/a","id":"CVE-2021-31858","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dnnsoftware:dotnetnuke","products":["dnnsoftware:dotnetnuke"],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2021-31859"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-31857"},"products":["n/a"],"published":"2022-07-20","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":"2024-08-03","vendors":["n/a"]},"summary":"Authenticated users can inject arbitrary scripts into profile biographies, potentially leading to session hijacking or malicious actions on behalf of other users.","url":"https://insights.sbomify.com/CVE-2021-31858/"}
