An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2016-4311 exists.\n\nAffected product: Wso2 Identity Server. 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-2016-4311/ (Markdown: https://insights.sbomify.com/CVE-2016-4311/index.md)","id":"CVE-2016-4311","markdown":"https://insights.sbomify.com/CVE-2016-4311/index.md","name":"CVE-2016-4311","record":{"aliases":["GHSA-839c-vxrv-chvh"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Identity Server","requires_auth":"none","summary":"Remote attackers can hijack privileged user sessions in WSO2 Identity Server via CSRF in the XACML flow feature.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"identity_server","vendor":"wso2"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Cross-site request forgery (CSRF) vulnerability in the XACML flow feature in WSO2 Identity Server 5.1.0 allows remote attackers to hijack the authentication of privileged users for requests that process XACML requests via an entitlement/eval-policy-submit.jsp request.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2016-08-16","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2016-08-16","kind":"exploitdb","ref":"40239","stars":null,"title":"WSO2 Identity Server 5.1.0 - Multiple Vulnerabilities"}],"tier":"weaponised"},"has_fix":null,"headline":"Cross-site request forgery in n/a","id":"CVE-2016-4311","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wso2:identity_server","products":["wso2:identity_server"],"type":"csrf","year":"2016"},"n_packages":0,"n_references":5,"next":{"headline":"XML external entity in n/a","id":"CVE-2016-4312"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2016-4309"},"products":["n/a"],"published":"2017-02-16","related":[{"cvss_score":8.6,"headline":"Denial-of-Service via Magic Link Authentication in WSO2 Identity Server Allows Service Unavailability","id":"CVE-2025-10470","kev_date_added":null,"published":"2026-05-11"},{"cvss_score":8.4,"headline":"Server-Side Template Injection via Velocity Template Engine in Multiple WSO2 Products Allows Remote Code Execution","id":"CVE-2025-12107","kev_date_added":null,"published":"2026-02-19"},{"cvss_score":7.5,"headline":"XML external entity in n/a","id":"CVE-2016-4312","kev_date_added":null,"published":"2017-02-16"},{"cvss_score":7.3,"headline":"Account Lock Bypass via Magic Link or Pass Key Authentication in WSO2 Identity Server Allows Unauthorized Access","id":"CVE-2025-10908","kev_date_added":null,"published":"2026-05-11"},{"cvss_score":6.8,"headline":"Auth bypass in WSO2 Identity Server","id":"CVE-2025-0663","kev_date_added":null,"published":"2025-09-23"},{"cvss_score":6.5,"headline":"Unauthenticated Server-Side Request Forgery (SSRF) in Multiple WSO2 Products via SOAP Admin Services","id":"CVE-2024-7073","kev_date_added":null,"published":"2025-06-02"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can hijack privileged user sessions in WSO2 Identity Server via CSRF in the XACML flow feature.","url":"https://insights.sbomify.com/CVE-2016-4311/"}
