Description

The PharStreamWrapper (aka phar-stream-wrapper) package 2.x before 2.1.1 and 3.x before 3.1.1 for TYPO3 does not prevent directory traversal, which allows attackers to bypass a deserialization protection mechanism, as demonstrated by a phar:///path/bad.phar/../good.phar URL.

CWEs

  • CWE-22 · Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
  • CWE-502 · Deserialization of Untrusted Data
