CVE-2010-3663
TYPO3 before 4.1.14, 4.2.x before 4.2.13, 4.3.x before 4.3.4 and 4.4.x before 4.4.1 contains an insecure default value of the variable fileDenyPattern which could allow remote attackers to execute arbitrary code on the backend.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.40%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
