A denial of service attack might be launched against the server if an unusually lengthy password (more than 10000000 characters) is supplied using the osTicket application. This can cause the website to go down or stop responding. When a long password is entered, this procedure will consume all available CPU and memory.

Cross Site Scripting vulnerability in the sanitize function in Enhancesoft osTicket 1.18.0 allows a remote attacker to escalate privileges via a crafted support ticket.

Enhancesoft osTicket versions 1.18.x prior to 1.18.3 and 1.17.x prior to 1.17.7 contain an arbitrary file read vulnerability in the ticket PDF export functionality. A remote attacker can submit a ticket containing crafted rich-text HTML that includes PHP filter expressions which are insufficiently sanitized before being processed by the mPDF PDF generator during export. When the attacker exports the ticket to PDF, the generated PDF can embed the contents of attacker-selected files from the server filesystem as bitmap images, allowing disclosure of sensitive local files in the context of the osTicket application user. This issue is exploitable in default configurations where guests may create tickets and access ticket status, or where self-registration is enabled.
