This vulnerability in prasathmani TinyFileManager (up to version 2.6) involves a path traversal flaw in the POST parameter handler of /filemanager.php. By manipulating the file[] argument, an attacker can traverse directories, potentially accessing unauthorized files on the server. The vulnerability is remotely exploitable without user interaction and requires low attack complexity and low privileges. Despite public disclosure of an exploit, the vendor has not provided a fix or mitigation.

Successful exploitation could allow an attacker to read arbitrary files on the affected system by traversing directories via the file[] POST parameter. This could lead to unauthorized disclosure of sensitive information. There is no indication of privilege escalation or code execution from the provided data. No known active exploitation has been reported.

No official patch or remediation is currently available from the vendor. Since the vendor did not respond to disclosure and no fixes have been published, users should consider restricting access to the TinyFileManager interface, such as limiting network exposure or implementing access controls to prevent unauthorized POST requests. Monitor vendor channels for any future updates or patches. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
