# CVE-2024-34358: TYPO3 vulnerable to an Uncontrolled Resource Consumption in the ShowImageController > Attackers can trigger excessive server-side thumbnail generation via unvalidated parameters, causing resource exhaustion and denial of service in TYPO3. - **Severity:** Medium 5.3 (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 14 May 2024 - **Updated:** 2 Aug 2024 - **Also known as:** GHSA-36g8-62qv-5957 ## What is CVE-2024-34358? CVE-2024-34358 is a medium-severity denial of service vulnerability in Typo3 Typo3, published on 14 May 2024. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description TYPO3 is an enterprise content management system. Starting in version 9.0.0 and prior to versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, and 13.1.1, the `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`). This allows adversaries to instruct the system to produce an arbitrary number of thumbnail images on the server side. TYPO3 versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, 13.1.1 fix the problem described. Weakness: CWE-770 (Allocation of Resources Without Limits or Throttling), CWE-347 (Improper Verification of Cryptographic Signature), CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) ## Which versions are affected by CVE-2024-34358? 10 open source packages ship an affected version, including typo3/cms-core. It affects 1 product. | Package | Ecosystem | Affected | Fixed in | | --- | --- | --- | --- | | `typo3/cms-core` | Packagist | From 10.0.0 | 10.4.45 | | `typo3/cms-core` | Packagist | From 10.0.0 | 10.4.45 | | `typo3/cms-core` | Packagist | From 11.0.0 | 11.5.37 | | `typo3/cms-core` | Packagist | From 11.0.0 | 11.5.37 | | `typo3/cms-core` | Packagist | From 12.0.0 | 12.4.15 | | `typo3/cms-core` | Packagist | From 12.0.0 | 12.4.15 | | `typo3/cms-core` | Packagist | From 13.0.0 | 13.1.1 | | `typo3/cms-core` | Packagist | From 13.0.0 | 13.1.1 | | `typo3/cms-core` | Packagist | From 9.0.0 | 9.5.48 | | `typo3/cms-core` | Packagist | From 9.0.0 | 9.5.48 | Products: Typo3 Typo3. ## How do I fix CVE-2024-34358?

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. 2. 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. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
