Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 15.6%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
Description
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.
