An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2019-9874 in the wild since at least 26 Mar 2025.\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-2019-9874/ (Markdown: https://insights.sbomify.com/CVE-2019-9874/index.md)","id":"CVE-2019-9874","markdown":"https://insights.sbomify.com/CVE-2019-9874/index.md","name":"CVE-2019-9874","record":{"aliases":["GHSA-wfwm-vf76-3692"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Sitecore CMS","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary code in Sitecore CMS by sending a malicious serialized .NET object in the CSRF token parameter.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cms","vendor":"sitecore"},{"product":"experience_platform","vendor":"sitecore"}],"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-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of Untrusted Data in the Sitecore.Security.AntiCSRF (aka anti CSRF) module in Sitecore CMS 7.0 to 7.2 and Sitecore XP 7.5 to 8.2 allows an unauthenticated attacker to execute arbitrary code by sending a serialized .NET object in the HTTP POST parameter __CSRFTOKEN.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2019/CVE-2019-9874.yaml","stars":null,"title":"Sitecore Experience Platform - Deserialization of Untrusted Data"}],"tier":"exploited"},"has_fix":null,"headline":"Sitecore CMS and Experience Platform (XP) Deserialization","id":"CVE-2019-9874","indexable":true,"kev":{"dateAdded":"2025-03-26","dueDate":"2025-04-16","knownRansomwareCampaignUse":"Unknown","product":"CMS and Experience Platform (XP)","requiredAction":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.","vendorProject":"Sitecore","vulnerabilityName":"Sitecore CMS and Experience Platform (XP) Deserialization Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2019"},"n_packages":0,"n_references":3,"next":{"headline":"Sitecore CMS and Experience Platform (XP) Deserialization","id":"CVE-2019-9875"},"packages":[],"prev":{"headline":"Hardcoded credentials in n/a","id":"CVE-2019-9873"},"products":["n/a"],"published":"2019-05-31","related":[{"cvss_score":8.8,"headline":"Sitecore CMS and Experience Platform (XP) Deserialization","id":"CVE-2019-9875","kev_date_added":"2025-03-26","published":"2019-05-31"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2019-11198","kev_date_added":null,"published":"2019-08-05"},{"cvss_score":5.4,"headline":"In Sitecore 8.2, there is reflected XSS in the shell/Applications/Tools/Run Program parameter.","id":"CVE-2017-11439","kev_date_added":null,"published":"2017-07-19"},{"cvss_score":4.9,"headline":"In Sitecore 8.2, there is absolute path traversal via the shell/Applications/Layouts/IDE.aspx fi parameter and the admin/LinqScratchPad.aspx Reference parameter.","id":"CVE-2017-11440","kev_date_added":null,"published":"2017-07-19"},{"cvss_score":4.3,"headline":"Cross-site scripting in n/a","id":"CVE-2014-100004","kev_date_added":null,"published":"2015-01-13"},{"cvss_score":4.3,"headline":"Cross-site scripting in n/a","id":"CVE-2009-2163","kev_date_added":null,"published":"2009-06-22"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"Unauthenticated attackers can execute arbitrary code in Sitecore CMS by sending a malicious serialized .NET object in the CSRF token parameter.","url":"https://insights.sbomify.com/CVE-2019-9874/"}
