An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2017-9248 in the wild since at least 3 Nov 2021.\n\nAffected product: n/a. 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-2017-9248/ (Markdown: https://insights.sbomify.com/CVE-2017-9248/index.md)","id":"CVE-2017-9248","markdown":"https://insights.sbomify.com/CVE-2017-9248/index.md","name":"CVE-2017-9248","record":{"aliases":["GHSA-mfqq-q5rf-3hvq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Telerik UI for ASP.NET","requires_auth":"none","summary":"Weak cryptographic protection in Telerik UI allows attackers to leak keys, enabling file access, XSS, and ViewState compromise.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"sitefinity","vendor":"progress"},{"product":"ui_for_asp.net_ajax","vendor":"telerik"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-522","name":"Insufficiently Protected Credentials"}],"description":"Telerik.Web.UI.dll in Progress Telerik UI for ASP.NET AJAX before R2 2017 SP1 and Sitefinity before 10.0.6412.0 does not properly protect Telerik.Web.UI.DialogParametersEncryptionKey or the MachineKey, which makes it easier for remote attackers to defeat cryptographic protection mechanisms, leading to a MachineKey leak, arbitrary file uploads or downloads, XSS, or ASP.NET ViewState compromise.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2018-01-16","github_poc":7,"max_poc_stars":178,"metasploit":0,"nuclei":0,"refs":[{"date":"2018-01-16T00:23:34Z","kind":"github_poc","ref":"https://github.com/bao7uo/dp_crypto","stars":178,"title":"Base64-based encryption oracle exploit for CVE-2017-9248 (Telerik UI for ASP.NET AJAX dialog handler)"},{"date":"2018-08-03T04:36:23Z","kind":"github_poc","ref":"https://github.com/capt-meelo/Telewreck","stars":96,"title":"A Burp extension to detect and exploit versions of Telerik Web UI vulnerable to CVE-2017-9248."},{"date":"2022-10-04T21:09:27Z","kind":"github_poc","ref":"https://github.com/blacklanternsecurity/dp_cryptomg","stars":61,"title":"Another tool for exploiting CVE-2017-9248, a cryptographic weakness in Telerik UI for ASP.NET AJAX dialog handler."},{"date":"2025-05-28T12:12:35Z","kind":"github_poc","ref":"https://github.com/0xsharz/telerik-scanner-cve-2017-9248","stars":2,"title":"Telerik CVE-2017-9248 Vulnerability Scanner"},{"date":"2018-01-24","kind":"exploitdb","ref":"43873","stars":null,"title":"Telerik UI for ASP.NET AJAX 2012.3.1308 \u003c 2017.1.118 - Encryption Keys Disclosure"},{"date":"2019-10-23T13:57:11Z","kind":"github_poc","ref":"https://github.com/ictnamanh/CVE-2017-9248","stars":0,"title":null},{"date":"2021-05-24T18:07:03Z","kind":"github_poc","ref":"https://github.com/oldboysonnt/dp","stars":0,"title":"Exploit CVE-2017-9248 Telerik ReMix from Paul Taylor's script.
