Title
Unauthenticated Arbitrary File Upload in Havalite CMS 1.1.7 (upload.php)

Description
A critical vulnerability exists in Havalite CMS version 1.1.7 (and possibly earlier), specifically within the upload.php script. Unauthenticated attackers can exploit this flaw by uploading files of any type, including executable scripts. Because the server fails to validate file type, extension, or authenticity, a remote attacker could successfully upload a malicious file (such as PHP shells or defacements) and execute commands with the privileges of the web server process. This enables a full compromise, including remote code execution, website defacement, exfiltration of sensitive data, or launching further attacks on users or internal systems. Reliable, low-complexity attack vectors exist, and no user interaction or authentication is required to exploit this issue.
