Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-49881 in the wild and no public exploit code.\n\nAffected product: IBM Transformation Extender Advanced. 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-2023-49881/ (Markdown: https://insights.sbomify.com/CVE-2023-49881/index.md)","id":"CVE-2023-49881","markdown":"https://insights.sbomify.com/CVE-2023-49881/index.md","name":"CVE-2023-49881","record":{"aliases":["GHSA-65v7-8599-57vr"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Transformation Extender","requires_auth":"low_privilege","summary":"An attacker can impersonate another user by exploiting session fixation due to sessions not being invalidated after logout in IBM Transformation Extender Advanced.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"transformation_extender_advanced","vendor":"ibm"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"IBM Transformation Extender Advanced 10.0.1 \n\ndoes not invalidate session after logout which could allow an authenticated user to impersonate another user on the system.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"IBM Transformation Extender Advanced session fixation","id":"CVE-2023-49881","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"IBM Transformation Extender Advanced information disclosure","id":"CVE-2023-49883"},"packages":[],"prev":{"headline":"IBM Financial Transaction Manager for SWIFT Services data manipulation","id":"CVE-2023-49880"},"products":["Transformation Extender Advanced"],"published":"2025-10-01","related":[{"cvss_score":9.8,"headline":"IBM Transformation Extender Advanced code execution","id":"CVE-2023-49886","kev_date_added":null,"published":"2025-10-06"},{"cvss_score":5.9,"headline":"IBM Transformation Extender Advanced information disclosure","id":"CVE-2023-49883","kev_date_added":null,"published":"2025-10-01"},{"cvss_score":5.1,"headline":"IBM Transformation Extender Advanced improper access control","id":"CVE-2023-50300","kev_date_added":null,"published":"2025-10-01"},{"cvss_score":4.3,"headline":"Information disclosure in Transformation Extender Advanced","id":"CVE-2021-29883","kev_date_added":null,"published":"2021-10-21"},{"cvss_score":1.9,"headline":"IBM Transformation Extender Advanced information disclosure","id":"CVE-2023-50301","kev_date_added":null,"published":"2025-10-01"}],"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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-01","vendors":["IBM"]},"summary":"An attacker can impersonate another user by exploiting session fixation due to sessions not being invalidated after logout in IBM Transformation Extender Advanced.","url":"https://insights.sbomify.com/CVE-2023-49881/"}
