An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2009-0256 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3/cms (Packagist): affected from 4.0.0; fixed in 4.0.10\n- typo3/cms (Packagist): affected from 4.0.0; fixed in 4.0.10\n- typo3/cms (Packagist): affected from 4.1.0; fixed in 4.1.8\n- typo3/cms (Packagist): affected from 4.1.0; fixed in 4.1.8\n- typo3/cms (Packagist): affected from 4.2.0; fixed in 4.2.4\n- typo3/cms (Packagist): affected from 4.2.0; fixed in 4.2.4\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-2009-0256/ (Markdown: https://insights.sbomify.com/CVE-2009-0256/index.md)","id":"CVE-2009-0256","markdown":"https://insights.sbomify.com/CVE-2009-0256/index.md","name":"CVE-2009-0256","record":{"aliases":["GHSA-q45q-5233-229p"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 CMS","requires_auth":"none","summary":"Remote attackers can hijack web sessions in TYPO3 via session fixation, leading to account takeover.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"typo3","vendor":"typo3"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Session fixation vulnerability in the authentication library in TYPO3 4.0.0 through 4.0.9, 4.1.0 through 4.1.7, and 4.2.0 through 4.2.3 allows remote attackers to hijack web sessions via unspecified vectors related to (1) frontend and (2) backend authentication.","ecosystems":["Packagist"],"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":"Authentication library in TYPO3 vulnerable to session fixation","id":"CVE-2009-0256","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"typo3:typo3","products":["typo3:typo3"],"type":"auth_bypass","year":"2009"},"n_packages":6,"n_references":6,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2009-0257"},"packages":[{"ecosystem":"Packagist","fixed":["4.0.10"],"introduced":["4.0.0"],"last_affected":[],"package":"typo3/cms","purl":null,"source":"GHSA-q45q-5233-229p"},{"ecosystem":"Packagist","fixed":["4.0.10"],"introduced":["4.0.0"],"last_affected":[],"package":"typo3/cms","purl":"pkg:composer/typo3/cms","source":"GHSA-q45q-5233-229p"},{"ecosystem":"Packagist","fixed":["4.1.8"],"introduced":["4.1.0"],"last_affected":[],"package":"typo3/cms","purl":null,"source":"GHSA-q45q-5233-229p"},{"ecosystem":"Packagist","fixed":["4.1.8"],"introduced":["4.1.0"],"last_affected":[],"package":"typo3/cms","purl":"pkg:composer/typo3/cms","source":"GHSA-q45q-5233-229p"},{"ecosystem":"Packagist","fixed":["4.2.4"],"introduced":["4.2.0"],"last_affected":[],"package":"typo3/cms","purl":null,"source":"GHSA-q45q-5233-229p"},{"ecosystem":"Packagist","fixed":["4.2.4"],"introduced":["4.2.0"],"last_affected":[],"package":"typo3/cms","purl":"pkg:composer/typo3/cms","source":"GHSA-q45q-5233-229p"}],"prev":{"headline":"Weak cryptography in n/a","id":"CVE-2009-0255"},"products":["n/a"],"published":"2009-01-22","related":[{"cvss_score":10,"headline":"Indexed Search Engine for TYPO3 Command Execution via Metacharacter Injection","id":"CVE-2009-0258","kev_date_added":null,"published":"2009-01-22"},{"cvss_score":9.8,"headline":"Typo3 SQL injection due to faulty prepared statements","id":"CVE-2011-3583","kev_date_added":null,"published":"2019-11-25"},{"cvss_score":9.8,"headline":"Typo3 Authentication Bypass","id":"CVE-2011-4628","kev_date_added":null,"published":"2019-11-06"},{"cvss_score":8.8,"headline":"Persisted Cross-Site Scripting in Frontend Rendering in typo3","id":"CVE-2023-24814","kev_date_added":null,"published":"2023-02-07"},{"cvss_score":8.8,"headline":"Cross-Site-Request-Forgery in Backend URI Handling in Typo3","id":"CVE-2021-41113","kev_date_added":null,"published":"2021-10-05"},{"cvss_score":8.8,"headline":"Missing Required Cryptographic Step Leading to Sensitive Information Disclosure in TYPO3 CMS","id":"CVE-2020-15098","kev_date_added":null,"published":"2020-07-29"},{"cvss_score":8.8,"headline":"Deserialization of Untrusted Data in TYPO3 CMS","id":"CVE-2020-11067","kev_date_added":null,"published":"2020-05-13"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can hijack web sessions in TYPO3 via session fixation, leading to account takeover.","url":"https://insights.sbomify.com/CVE-2009-0256/"}
