TYPO3 vulnerable to Arbitrary Code Execution via Form Framework

Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 0.83% (FIRST EPSS); higher than 57.3% of all records.
  • 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 (Packagist) 10.4.33, 11.5.20, 12.1.1; typo3/cms-core (Packagist) 10.4.33, 11.5.20, 12.1.1.

Low priority for now. Upgrade to typo3/cms (Packagist) 10.4.33, 11.5.20, 12.1.1; typo3/cms-core (Packagist) 10.4.33, 11.5.20, 12.1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

TYPO3 is an open source PHP based web content management system. Versions prior to 8.7.49, 9.5.38, 10.4.33, 11.5.20, and 12.1.1 are vulnerable to Code Injection. Due to the lack of separating user-submitted data from the internal configuration in the Form Designer backend module, it is possible to inject code instructions to be processed and executed via TypoScript as PHP code. The existence of individual TypoScript instructions for a particular form item and a valid backend user account with access to the form module are needed to exploit this vulnerability. This issue is patched in versions 8.7.49 ELTS, 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1.
