Not scored
Published
Check this codebase for GHSA-x4rj-f7m6-42c3 and fix it if it is affected.
What it is: GHSA-x4rj-f7m6-42c3 is an authentication bypass vulnerability in typo3/cms-core, published on 30 May 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of GHSA-x4rj-f7m6-42c3 in the wild and no public exploit code.
Affected packages and fixed versions:
- typo3/cms-core (Packagist): affected from 7.0.0; fixed in 7.6.30
- typo3/cms-core (Packagist): affected from 7.0.0; fixed in 7.6.30
- typo3/cms-core (Packagist): affected from 8.0.0; fixed in 8.7.17
- typo3/cms-core (Packagist): affected from 8.0.0; fixed in 8.7.17
- typo3/cms-core (Packagist): affected from 9.0.0; fixed in 9.3.2
- typo3/cms-core (Packagist): affected from 9.0.0; fixed in 9.3.2
Task:
1. 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.

What is GHSA-x4rj-f7m6-42c3?
GHSA-x4rj-f7m6-42c3 is an authentication bypass vulnerability in typo3/cms-core, published on 30 May 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
It has been discovered that TYPO3’s Salted Password system extension (which is a mandatory system component) is vulnerable to Authentication Bypass when using hashing methods which are related by PHP class inheritance. In standard TYPO3 core distributions stored passwords using the blowfish hashing algorithm can be overridden when using MD5 as the default hashing algorithm by just knowing a valid username. Per default the Portable PHP hashing algorithm (PHPass) is used which is not vulnerable.
