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-2020-15099 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3/cms (Packagist): affected from 10.0.0; fixed in 10.4.6\n- typo3/cms (Packagist): affected from 10.0.0; fixed in 10.4.6\n- typo3/cms (Packagist): affected from 9.0.0; fixed in 9.5.20\n- typo3/cms (Packagist): affected from 9.0.0; fixed in 9.5.20\n- typo3 (Bitnami): affected from 9.0.0; fixed in 9.5.20, 10.4.6\n- typo3/cms-core (Packagist): affected from 10.0.0; fixed in 10.4.6\n- typo3/cms-core (Packagist): affected from 10.0.0; fixed in 10.4.6\n- typo3/cms-core (Packagist): affected from 9.0.0; fixed in 9.5.20\n- typo3/cms-core (Packagist): affected from 9.0.0; fixed in 9.5.20\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-2020-15099/ (Markdown: https://insights.sbomify.com/CVE-2020-15099/index.md)","id":"CVE-2020-15099","markdown":"https://insights.sbomify.com/CVE-2020-15099/index.md","name":"CVE-2020-15099","record":{"aliases":["BIT-typo3-2020-15099","GHSA-3x94-fv5h-5q2c"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"TYPO3 CMS","requires_auth":"none","summary":"Attackers with valid HMAC keys can read sensitive configuration files, leading to database access and remote code execution in TYPO3 CMS.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"typo3","vendor":"typo3"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In TYPO3 CMS greater than or equal to 9.0.0 and less than 9.5.20, and greater than or equal to 10.0.0 and less than 10.4.6, in a case where an attacker manages to generate a valid cryptographic message authentication code (HMAC-SHA1) - either by using a different existing vulnerability or in case the internal encryptionKey was exposed - it is possible to retrieve arbitrary files of a TYPO3 installation. This includes the possibility to fetch typo3conf/LocalConfiguration.php, which again contains the encryptionKey as well as credentials of the database management system being used. In case a database server is directly accessible either via internet or in a shared hosting network, this allows the ability to completely retrieve, manipulate or delete database contents. This includes creating an administration user account - which can be used to trigger remote code execution by injecting custom extensions.
