Description:
ajann has discovered a vulnerability in FD Script, which can be exploited by malicious people to gain knowledge of sensitive information.
The vulnerability is caused due to an input validation error in download.php when processing arguments passed to the "fname" parameter. This can be exploited to download files that are configured as non-downloadable (e.g. .PHP, .HTM, .HTML, etc...) within the FD Script directory and subdirectories by prepending the target file name with "./".
The vulnerability is confirmed in version 1.3.2. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly validated.
Do not put sensitive files or scripts in the FdScript directory or subdirectories.
