An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2018-15812 exists.\n\nAffected packages and fixed versions:\n- DotNetNuke.Core (NuGet): affected from 9.2.0; fixed in 9.2.2\n- DotNetNuke.Core (NuGet): affected from 9.2.0; fixed in 9.2.2\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-2018-15812/ (Markdown: https://insights.sbomify.com/CVE-2018-15812/index.md)","id":"CVE-2018-15812","markdown":"https://insights.sbomify.com/CVE-2018-15812/index.md","name":"CVE-2018-15812","record":{"aliases":["GHSA-pf46-gqg9-j3v3"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"DNN CMS","requires_auth":"none","summary":"Attackers can exploit low entropy in encryption keys to bypass security controls in DNN CMS installations.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dotnetnuke","vendor":"dnnsoftware"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-331","name":"Insufficient Entropy"}],"description":"DNN (aka DotNetNuke) 9.2 through 9.2.1 incorrectly converts encryption key source values, resulting in lower than expected entropy.","ecosystems":["NuGet"],"exploits":{"exploitdb":1,"first_seen":"2017-07-20","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2017-07-20","kind":"metasploit","ref":"exploit/windows/http/dnn_cookie_deserialization_rce","stars":null,"title":"DotNetNuke Cookie Deserialization Remote Code Excecution"},{"date":"2020-04-16","kind":"exploitdb","ref":"48336","stars":null,"title":"DotNetNuke - Cookie Deserialization Remote Code Execution (Metasploit)"}],"tier":"weaponised"},"has_fix":true,"headline":"Insufficient Entropy in DotNetNuke","id":"CVE-2018-15812","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":"dnnsoftware:dotnetnuke","products":["dnnsoftware:dotnetnuke"],"type":"weak_cryptography","year":"2018"},"n_packages":2,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2018-15813"},"packages":[{"ecosystem":"NuGet","fixed":["9.2.2"],"introduced":["9.2.0"],"last_affected":[],"package":"DotNetNuke.Core","purl":null,"source":"GHSA-pf46-gqg9-j3v3"},{"ecosystem":"NuGet","fixed":["9.2.2"],"introduced":["9.2.0"],"last_affected":[],"package":"DotNetNuke.Core","purl":"pkg:nuget/DotNetNuke.Core","source":"GHSA-pf46-gqg9-j3v3"}],"prev":{"headline":"DotNetNuke (DNN) Inadequate Encryption Strength","id":"CVE-2018-15811"},"products":["n/a"],"published":"2019-07-03","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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can exploit low entropy in encryption keys to bypass security controls in DNN CMS installations.","url":"https://insights.sbomify.com/CVE-2018-15812/"}
