What is CVE-2017-15580?

osTicket version 1.10.1 contains a flaw in its handling of file uploads. The application permits users to upload files with an '.html' extension without properly validating the content of these files. This oversight allows attackers to exploit the system by uploading malicious files disguised with a different extension, such as .exe. Consequently, this facilitates unauthorized file uploads, potentially leading to execution of harmful scripts on the web server.
