Osticket : Security Vulnerabilities, CVEs, CVSS score >= 9

SSRF exists in osTicket before 1.14.3, where an attacker can add malicious file to server or perform port scanning.

osTicket 1.10.1 provides a functionality to upload 'html' files with associated formats. However, it does not properly validate the uploaded file's contents and thus accepts any type of file, such as with a tickets.php request that is modified with a .html extension changed to a .exe extension. An attacker can leverage this vulnerability to upload arbitrary files on the web application having malicious content.

In osTicket before 1.10.1, SQL injection is possible by constructing an array via use of square brackets at the end of a parameter name, as demonstrated by the key parameter to file.php.
