Tiny File Manager through 2.6 contains a server-side request forgery (SSRF) vulnerability in the URL upload feature. Due to insufficient validation of user-supplied URLs, an attacker can send crafted requests to localhost by using http://www.127.0.0.1.example.com/ or a similarly constructed domain name. This may lead to unauthorized port scanning or access to internal-only services.
A flaw has been found in prasathmani TinyFileManager up to 2.6. Affected by this issue is some unknown functionality of the file tinyfilemanager.php. This manipulation of the argument fullpath causes path traversal. Remote exploitation of the attack is possible. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
