CVE-2023-47127: Weak Authentication in Session Handling in typo3/cms-core

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.56% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: typo3/cms-core (Packagist) 10.4.41, 11.5.33, 12.4.8.

Low priority for now. Upgrade to typo3/cms-core (Packagist) 10.4.41, 11.5.33, 12.4.8 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

TYPO3 is an open source PHP based web content management system released under the GNU GPL. In typo3 installations there are always at least two different sites. Eg. first.example.org and second.example.com. In affected versions a session cookie generated for the first site can be reused on the second site without requiring additional authentication. This vulnerability has been addressed in versions 8.7.55, 9.5.44, 10.4.41, 11.5.33, and 12.4.8. Users are advised to upgrade. There are no known workarounds for this vulnerability.
