Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Unisharp/laravel filemanager, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Versions of the package unisharp/laravel-filemanager before 2.9.1 are vulnerable to Remote Code Execution (RCE) through using a valid mimetype and inserting the . character after the php file extension. This allows the attacker to execute malicious code.
