Miggo AIRoot Cause Analysis

The vulnerability arises from two key functions:

  1. getoptions() in dompdf.php lacked protocol checks for the 'input_file' parameter, enabling remote file inclusion. Attackers could supply URLs pointing to malicious PHP files.
  2. load_html() in dompdf.cls.php executed embedded PHP code via eval if 'enable_php' was enabled. Combined with remote file inclusion, this allowed code execution. The patch removed the PHP evaluation code and added protocol restrictions, confirming these functions' roles in the vulnerability.
