The vulnerability resides within the \u003ccode\u003efilemanager/dialog.php\u003c/code\u003e script and permits an unauthenticated, remote attacker to perform unrestricted file uploads. Because the vendor has provided no response and the software is no longer supported, this flaw will remain unpatched, exposing environments that continue to run this legacy component. Publicly available exploit code exists, increasing the risk of exploitation. Defenders should prioritize identifying instances of ResponsiveFilemanager in their environments and replacing the legacy file management component, as no security updates will be issued for this software.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker performs reconnaissance to identify web servers running Trippo ResponsiveFilemanager.\u003c/li\u003e\n\u003cli\u003eAttacker interacts with the publicly accessible \u003ccode\u003efilemanager/dialog.php\u003c/code\u003e endpoint.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious HTTP POST request targeting the file upload functionality.\u003c/li\u003e\n\u003cli\u003eAttacker bypasses missing or inadequate file type validation mechanisms within the script.\u003c/li\u003e\n\u003cli\u003eAttacker uploads a malicious script (e.g., a web shell) to a web-accessible directory.\u003c/li\u003e\n\u003cli\u003eAttacker confirms the location of the uploaded file via server responses or directory traversal.\u003c/li\u003e\n\u003cli\u003eAttacker executes the uploaded script by requesting the file directly via the web server.\u003c/li\u003e\n\u003cli\u003eAttacker gains persistent remote code execution (RCE) on the underlying host.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation allows remote attackers to gain full control over the web server by uploading and executing arbitrary web shells.
