Official Description
The Backend History Module in TYPO3 4.5.x before 4.5.21, 4.6.x before 4.6.14, and 4.7.x before 4.7.6 does not properly restrict access, which allows remote authenticated editors to read the history of arbitrary records via a crafted URL.
Technical Analysis
CVE-2012-6146 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
