Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2017-9822 in the wild since at least 3 Nov 2021, including in ransomware campaigns.\n\nAffected packages and fixed versions:\n- DotNetNuke.Core (NuGet): affected all versions; fixed in 9.1.1\n- DotNetNuke.Core (NuGet): affected all versions; fixed in 9.1.1\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-2017-9822/ (Markdown: https://insights.sbomify.com/CVE-2017-9822/index.md)","id":"CVE-2017-9822","markdown":"https://insights.sbomify.com/CVE-2017-9822/index.md","name":"CVE-2017-9822","record":{"aliases":["GHSA-x2rg-fmcv-crq5"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"DNN CMS","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution on DNN sites by exploiting a deserialization vulnerability in cookies.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hpe","cpe":[{"product":"dotnetnuke","vendor":"dnnsoftware"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"DNN (aka DotNetNuke) before 9.1.1 has Remote Code Execution via a cookie, aka \"2017-08 (Critical) Possible remote code execution on DNN sites.\"","ecosystems":["NuGet"],"exploits":{"exploitdb":1,"first_seen":"2017-07-20","github_poc":3,"max_poc_stars":22,"metasploit":1,"nuclei":1,"refs":[{"date":"2020-08-28T12:45:44Z","kind":"github_poc","ref":"https://github.com/murataydemir/CVE-2017-9822","stars":22,"title":"[CVE-2017-9822] DotNetNuke Cookie Deserialization Remote Code Execution (RCE)"},{"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 -
