## Technical details

An unrestricted file upload vulnerability (CWE-434) exists in the ticket attachments functionality of Paymenter. A malicious authenticated user with low privileges can upload arbitrary files, such as PHP scripts, to the server. Because these files are stored in a web-accessible directory without sufficient execution restrictions, an attacker can execute arbitrary system commands under the context of the web server user. This allows for full application and server compromise, including database extraction and credential theft. The issue is resolved in version 1.2.11.
