SugarCRM <= 14.0.0 (css/preview) LESS Code Injection Vulnerability
------------------------------------------------------------------


[-] Software Link:

https://www.sugarcrm.com


[-] Affected Versions:

All commercial versions before 13.0.4 and 14.0.1.


[-] 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.
