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-2022-23500 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- typo3/cms-core (Packagist): affected from 10.0.0; fixed in 10.4.33\n- typo3/cms-core (Packagist): affected from 10.0.0; fixed in 10.4.33\n- typo3/cms-core (Packagist): affected from 11.0.0; fixed in 11.5.20\n- typo3/cms-core (Packagist): affected from 11.0.0; fixed in 11.5.20\n- typo3/cms-core (Packagist): affected from 9.0.0; fixed in 9.5.38\n- typo3/cms-core (Packagist): affected from 9.0.0; fixed in 9.5.38\n- typo3 (Bitnami): affected from 9.0.0; fixed in 9.5.38, 10.4.33, 11.5.20\n- typo3/cms (Packagist): affected from 10.0.0; fixed in 10.4.33\n- typo3/cms (Packagist): affected from 10.0.0; fixed in 10.4.33\n- typo3/cms (Packagist): affected from 11.0.0; fixed in 11.5.20\n- typo3/cms (Packagist): affected from 11.0.0; fixed in 11.5.20\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-2022-23500/ (Markdown: https://insights.sbomify.com/CVE-2022-23500/index.md)","id":"CVE-2022-23500","markdown":"https://insights.sbomify.com/CVE-2022-23500/index.md","name":"CVE-2022-23500","record":{"aliases":["BIT-typo3-2022-23500","GHSA-8c28-5mp7-v24h"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 CMS","requires_auth":"none","summary":"Attackers can cause a denial of service in TYPO3 by triggering uncontrolled recursion through invalid resource requests, exhausting server resources.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"typo3","vendor":"typo3"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"TYPO3 is an open source PHP based web content management system. In versions prior to 9.5.38, 10.4.33, 11.5.20, and 12.1.1, requesting invalid or non-existing resources via HTTP triggers the page error handler, which again could retrieve content to be shown as an error message from another page. This leads to a scenario in which the application is calling itself recursively - amplifying the impact of the initial attack until the limits of the web server are exceeded. This vulnerability is very similar, but not identical, to the one described in CVE-2021-21359.
