Description

An issue was discovered in the direct_mail (aka Direct Mail) extension through 9.5.1 for TYPO3. The Configuration backend module of the extension allows an authenticated user to write to an arbitrary TSConfig page for folders configured as Direct Mail. Exploiting this may lead to Configuration Injection (TYPO3 10.4 and above) and to Arbitrary Code Execution (TYPO3 9.5 and below). A valid backend user account, with access to the Direct Mail Configuration backend module, is needed to exploit this.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for directmailteam/direct-mail, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update directmailteam/direct-mail to 9.5.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-50461 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Frequently Asked Questions

The “Configuration” backend module of the extension allows an authenticated user to write arbitrary page TSConfig for folders configured as “Direct Mail”. Exploiting the vulnerability may lead to Configuration Injection (TYPO3 10.4 and above) and to Arbitrary Code Execution (TYPO3 9.5 and below). A valid backend user account having access to the Direct Mail "Configuration" backend module is needed in order to exploit this vulnerability.
