An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-5656 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.cxf:cxf-core (Maven): affected all versions; fixed in 3.0.13\n- org.apache.cxf:cxf-core (Maven): affected all versions; fixed in 3.0.13\n- org.apache.cxf:cxf-core (Maven): affected from 3.1.0; fixed in 3.1.11\n- org.apache.cxf:cxf-core (Maven): affected from 3.1.0; fixed in 3.1.11\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-2017-5656/ (Markdown: https://insights.sbomify.com/CVE-2017-5656/index.md)","id":"CVE-2017-5656","markdown":"https://insights.sbomify.com/CVE-2017-5656/index.md","name":"CVE-2017-5656","record":{"aliases":["GHSA-v936-x3j5-c76j"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache CXF STSClient","requires_auth":"none","summary":"An attacker can craft a token to impersonate another user by exploiting flawed token caching in Apache CXF STSClient.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"cxf","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"Apache CXF's STSClient before 3.1.11 and 3.0.13 uses a flawed way of caching tokens that are associated with delegation tokens, which means that an attacker could craft a token which would return an identifer corresponding to a cached token for another user.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Session Fixation in Apache CXF","id":"CVE-2017-5656","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"apache:cxf","products":["apache:cxf"],"type":"auth_bypass","year":"2017"},"n_packages":4,"n_references":11,"next":{"headline":"Apache Archiva vulnerable to Cross Site Request Forgery","id":"CVE-2017-5657"},"packages":[{"ecosystem":"Maven","fixed":["3.0.13"],"introduced":["0"],"last_affected":[],"package":"org.apache.cxf:cxf-core","purl":null,"source":"GHSA-v936-x3j5-c76j"},{"ecosystem":"Maven","fixed":["3.0.13"],"introduced":["0"],"last_affected":[],"package":"org.apache.cxf:cxf-core","purl":"pkg:maven/org.apache.cxf/cxf-core","source":"GHSA-v936-x3j5-c76j"},{"ecosystem":"Maven","fixed":["3.1.11"],"introduced":["3.1.0"],"last_affected":[],"package":"org.apache.cxf:cxf-core","purl":null,"source":"GHSA-v936-x3j5-c76j"},{"ecosystem":"Maven","fixed":["3.1.11"],"introduced":["3.1.0"],"last_affected":[],"package":"org.apache.cxf:cxf-core","purl":"pkg:maven/org.apache.cxf/cxf-core","source":"GHSA-v936-x3j5-c76j"}],"prev":{"headline":"Information disclosure in Apache Ambari","id":"CVE-2017-5655"},"products":["Apache CXF"],"published":"2017-04-18","related":[{"cvss_score":10,"headline":"XML Signature/Encryption Not Validated in Apache CXF","id":"CVE-2012-2379","kev_date_added":null,"published":"2013-01-03"},{"cvss_score":9.8,"headline":"Apache CXF: Unsafe deserialization of inbound JMS ObjectMessage","id":"CVE-2026-66909","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":9.8,"headline":"Apache CXF: DefaultEncryptingCodeDataProvider allows unlimited authorization code replay","id":"CVE-2026-68079","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":9.8,"headline":"Apache CXF: OAuth2: Inverted IP Binding Check Defeats Security Control","id":"CVE-2026-50628","kev_date_added":null,"published":"2026-06-12"},{"cvss_score":9.8,"headline":"Apache CXF: Untrusted JMS configuration can lead to RCE","id":"CVE-2025-48913","kev_date_added":null,"published":"2025-08-08"},{"cvss_score":9.8,"headline":"Apache CXF SSRF Vulnerability","id":"CVE-2022-46364","kev_date_added":null,"published":"2022-12-13"},{"cvss_score":9.8,"headline":"Potential session hijack in Apache CXF","id":"CVE-2019-12419","kev_date_added":null,"published":"2019-11-06"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Apache Software Foundation"]},"summary":"An attacker can craft a token to impersonate another user by exploiting flawed token caching in Apache CXF STSClient.","url":"https://insights.sbomify.com/CVE-2017-5656/"}
