5DescriptionNVD
A security vulnerability has been detected in osTicket up to 1.18.3. Impacted is an unknown function of the file include/class.dispatcher.php of the component Dispatcher. The manipulation of the argument _method leads to cross-site request forgery. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through a pull request but has not reacted yet.
AnalysisAI
Cross-site request forgery in osTicket up to version 1.18.3 allows remote attackers to bypass CSRF token validation by manipulating the _method parameter via GET requests, enabling unauthorized state-changing operations without user interaction beyond clicking a malicious link. The vulnerability exploits improper HTTP method emulation in the Dispatcher component and has publicly available proof-of-concept code; a vendor patch is available.
