info:
|
|
name: Laravel <5.5.21 - Information Disclosure
|
|
author: j4vaovo
|
|
severity: high
|
|
description: |
|
|
Laravel through 5.5.21 is susceptible to information disclosure. An attacker can obtain sensitive information such as externally usable passwords via a direct request for the /.env URI. NOTE: CVE pertains only to the writeNewEnvironmentFileWith function in src/Illuminate/Foundation/Console/KeyGenerateCommand.php, which uses file_put_contents without restricting .env permissions. The .env filename is not used exclusively by Laravel.
|
|
impact: |
|
|
An attacker can exploit this vulnerability to gain sensitive information from the application.
|
|
remediation: |
|
|
Upgrade Laravel to version 5.5.21 or higher to fix the information disclosure vulnerability.
