{"id":"CVE-2024-34358","aliases":["GHSA-36g8-62qv-5957"],"url":"https://o3.security/vulnerability/CVE-2024-34358","summary":"TYPO3 vulnerable to an Uncontrolled Resource Consumption in the ShowImageController","details":"### Problem\nThe `ShowImageController` (_eID tx_cms_showpic_) lacks a cryptographic HMAC-signature on the `frame` HTTP query parameter (e.g. `/index.php?eID=tx_cms_showpic?file=3&...&frame=12345`).\nThis allows adversaries to instruct the system to produce an arbitrary number of thumbnail images on the server side.\n\n### Solution\nUpdate to TYPO3 versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, 13.1.1 that fix the problem described.\n\n#### ℹ️ **Strong security defaults - Manual actions required**\n\nThe `frame` HTTP query parameter is now ignored, since it could not be used by core APIs.\n\nThe new feature flag `security.frontend.allowInsecureFrameOptionInShowImageController` – which is disabled per default – can be used to reactivate the previous behavior.\n\n### Credits\nThanks to TYPO3 security team member Torben Hansen who reported this issue and to TYPO3 core & security team members Benjamin Mack and Benjamin Franzke who fixed the issue.\n\n### References\n* [TYPO3-CORE-SA-2024-010](https://typo3.org/security/advisory/typo3-core-sa-2024-010)\n","published":"2024-05-14T14:26:36.422Z","modified":"2026-08-27T03:30:40.624183739Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"9.5.48"},{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"10.4.45"},{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"11.5.37"},{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"12.4.15"},{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"13.1.1"}],"fix":{"url":"https://github.com/TYPO3/typo3/commit/05c95fed869a1a6dcca06c7077b83b6ea866ff14","label":"TYPO3/typo3@05c95fe"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/34xxx/CVE-2024-34358.json"},{"type":"ADVISORY","url":"https://github.com/TYPO3/typo3/security/advisories/GHSA-36g8-62qv-5957"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-34358"},{"type":"ADVISORY","url":"https://typo3.org/security/advisory/typo3-core-sa-2024-010"},{"type":"FIX","url":"https://github.com/TYPO3/typo3/commit/05c95fed869a1a6dcca06c7077b83b6ea866ff14"},{"type":"FIX","url":"https://github.com/TYPO3/typo3/commit/1e70ebf736935413b0531004839362b4fb0755a5"},{"type":"FIX","url":"https://github.com/TYPO3/typo3/commit/df7909b6a1cf0f12a42994d0cc3376b607746142"},{"type":"PACKAGE","url":"https://github.com/TYPO3/typo3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T03:30:40.624183739Z"}}
