Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

Ignition before 2.5.2, as used in Laravel and other products, allows unauthenticated remote attackers to execute arbitrary code because of insecure usage of file_get_contents() and file_put_contents(). This is exploitable on sites using debug mode with Laravel before 8.4.2.

Technical Analysis

Added to CISA KEV on Sept. 18, 2023, but exploited for at least the past two years. Vuln only affects sites with debug mode enabled, which are evidently more common than one perhaps would’ve thought. In any event, it’s a two-plus-year-old vuln — please patch it.
