Vulnerabilities

osTicket prior to v1.17.6 and v1.18.2 are vulnerable to Broken Access Control Vulnerability in /scp/ajax.php.

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.

osTicket 1.10.1 allows arbitrary client-side JavaScript code execution on victims who click a crafted support/scp/tickets.php?status= link, aka XSS. Session ID and data theft may follow as well as the possibility of bypassing CSRF protections, injection of iframes to establish communication channels, etc. The vulnerability is present after login into the application. This affects a different tickets.php file than CVE-2015-1176.

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.
