Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2015-5956 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3/cms (Packagist): affected from 4.0 up to 4.5.40; no fix listed\n- typo3/cms (Packagist): affected from 4.0 up to 4.5.40; no fix listed\n- typo3/cms (Packagist): affected from 6.0; fixed in 6.2.15\n- typo3/cms (Packagist): affected from 6.0; fixed in 6.2.15\n- typo3/cms (Packagist): affected from 7.0; fixed in 7.4.0\n- typo3/cms (Packagist): affected from 7.0; fixed in 7.4.0\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-2015-5956/ (Markdown: https://insights.sbomify.com/CVE-2015-5956/index.md)","id":"CVE-2015-5956","markdown":"https://insights.sbomify.com/CVE-2015-5956/index.md","name":"CVE-2015-5956","record":{"aliases":["GHSA-989h-wv8x-933p"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 CMS","requires_auth":"low_privilege","summary":"Authenticated users can bypass XSS filters via base64 encoded data URIs in TYPO3, enabling cross-site scripting attacks.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"typo3","vendor":"typo3"}],"cvss":{"score":3.5,"severity":"low","source":"nvd","vector":"AV:N/AC:M/Au:S/C:N/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The sanitizeLocalUrl function in TYPO3 6.x before 6.2.15, 7.x before 7.4.0, 4.5.40, and earlier allows remote authenticated users to bypass the XSS filter and conduct cross-site scripting (XSS) attacks via a base64 encoded data URI, as demonstrated by the (1) returnUrl parameter to show_rechis.php and the (2) redirect_url parameter to index.php.","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":"TYPO3 cross-site scripting (XSS)","id":"CVE-2015-5956","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"typo3:typo3","products":["typo3:typo3"],"type":"xss","year":"2015"},"n_packages":6,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2015-5957"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["4.0"],"last_affected":["4.5.40"],"package":"typo3/cms","purl":null,"source":"GHSA-989h-wv8x-933p"},{"ecosystem":"Packagist","fixed":[],"introduced":["4.0"],"last_affected":["4.5.40"],"package":"typo3/cms","purl":"pkg:composer/typo3/cms","source":"GHSA-989h-wv8x-933p"},{"ecosystem":"Packagist","fixed":["6.2.15"],"introduced":["6.0"],"last_affected":[],"package":"typo3/cms","purl":null,"source":"GHSA-989h-wv8x-933p"},{"ecosystem":"Packagist","fixed":["6.2.15"],"introduced":["6.0"],"last_affected":[],"package":"typo3/cms","purl":"pkg:composer/typo3/cms","source":"GHSA-989h-wv8x-933p"},{"ecosystem":"Packagist","fixed":["7.4.0"],"introduced":["7.0"],"last_affected":[],"package":"typo3/cms","purl":null,"source":"GHSA-989h-wv8x-933p"},{"ecosystem":"Packagist","fixed":["7.4.0"],"introduced":["7.0"],"last_affected":[],"package":"typo3/cms","purl":"pkg:composer/typo3/cms","source":"GHSA-989h-wv8x-933p"}],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2015-5955"},"products":["n/a"],"published":"2015-09-16","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":"2024-08-06","vendors":["n/a"]},"summary":"Authenticated users can bypass XSS filters via base64 encoded data URIs in TYPO3, enabling cross-site scripting attacks.","url":"https://insights.sbomify.com/CVE-2015-5956/"}
