Title: My Getright Remote Arbitrary File Overwrite Vulnerability
Severity: MODERATE
Description:
MyGetright is a download manager for Windows.
The program accepts custom "skins" from remote websites. A '.dld' file is used to specify paths to various resources, including graphics, file permissions, etc.
If the maliciously-composed .dld file lists pathnames which contain long sequences of extraneous data, the program's skin data can be mis-parsed, causing the program's user interface to freeze while the program itself continues to operate.
.dld files can specify download paths via a field called 'filepath'. If a file is specified for download, and the file already exists on the user's system, the frozen UI will fail to notify the user, and the file will be overwritten without user prompting or confirmation.
If this field contains values including '/../' sequences, the filepath specified can extend beyond the normal directory structure used by My Getright, to the entire filesystem. As a result, arbitrary files on the target may be overwritten.
