Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2012-3527 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3/cms (Packagist): affected from 4.5.0; fixed in 4.5.19\n- typo3/cms (Packagist): affected from 4.5.0; fixed in 4.5.19\n- typo3/cms (Packagist): affected from 4.6.0; fixed in 4.6.12\n- typo3/cms (Packagist): affected from 4.6.0; fixed in 4.6.12\n- typo3/cms (Packagist): affected from 4.7.0; fixed in 4.7.4\n- typo3/cms (Packagist): affected from 4.7.0; fixed in 4.7.4\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-2012-3527/ (Markdown: https://insights.sbomify.com/CVE-2012-3527/index.md)","id":"CVE-2012-3527","markdown":"https://insights.sbomify.com/CVE-2012-3527/index.md","name":"CVE-2012-3527","record":{"aliases":["GHSA-m4hw-r893-xh4g"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 CMS","requires_auth":"low_privilege","summary":"Authenticated backend users can execute arbitrary PHP code via unsafe deserialization in the TYPO3 help system.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"typo3","vendor":"typo3"}],"cvss":{"score":4.6,"severity":"medium","source":"nvd","vector":"AV:N/AC:H/Au:S/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"view_help.php in the backend help system in TYPO3 4.5.x before 4.5.19, 4.6.x before 4.6.12 and 4.7.x before 4.7.4 allows remote authenticated backend users to unserialize arbitrary objects and possibly execute arbitrary PHP code via an unspecified parameter, related to a \"missing signature (HMAC).\"","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 allows remote authenticated backend users to unserialize arbitrary objects","id":"CVE-2012-3527","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"debian:debian_linux","products":["debian:debian_linux","typo3:typo3"],"type":"deserialization","year":"2012"},"n_packages":6,"n_references":6,"next":{"headline":"Typo3 Backend XSS Vulnerability","id":"CVE-2012-3528"},"packages":[{"ecosystem":"Packagist","fixed":["4.5.19"],"introduced":["4.5.0"],"last_affected":[],"package":"typo3/cms","purl":null,"source":"GHSA-m4hw-r893-xh4g"},{"ecosystem":"Packagist","fixed":["4.5.19"],"introduced":["4.5.0"],"last_affected":[],"package":"typo3/cms","purl":"pkg:composer/typo3/cms","source":"GHSA-m4hw-r893-xh4g"},{"ecosystem":"Packagist","fixed":["4.6.12"],"introduced":["4.6.0"],"last_affected":[],"package":"typo3/cms","purl":null,"source":"GHSA-m4hw-r893-xh4g"},{"ecosystem":"Packagist","fixed":["4.6.12"],"introduced":["4.6.0"],"last_affected":[],"package":"typo3/cms","purl":"pkg:composer/typo3/cms","source":"GHSA-m4hw-r893-xh4g"},{"ecosystem":"Packagist","fixed":["4.7.4"],"introduced":["4.7.0"],"last_affected":[],"package":"typo3/cms","purl":null,"source":"GHSA-m4hw-r893-xh4g"},{"ecosystem":"Packagist","fixed":["4.7.4"],"introduced":["4.7.0"],"last_affected":[],"package":"typo3/cms","purl":"pkg:composer/typo3/cms","source":"GHSA-m4hw-r893-xh4g"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2012-3526"},"products":["n/a"],"published":"2012-09-05","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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 backend users can execute arbitrary PHP code via unsafe deserialization in the TYPO3 help system.","url":"https://insights.sbomify.com/CVE-2012-3527/"}
