BitRaider Streaming Client 1.3.3.4098 Local Privilege Escalation Vulnerability
 
 
Vendor: BitRaider, LLC
Product web page: http://www.bitraider.com
Affected version: 1.3.3.4098
 
Summary: BitRaider is a video game streaming and download service.
 
Desc: BitRaider contains a flaw that leads to unauthorized privileges being gained.
The issue is due to the program granting improper permissions with the 'F' flag for
the 'Users' group, which makes the entire 'BitRaider' directory and its sub directories
and files world-writable. This may allow a local attacker to change an executable file
with a binary file and gain elevated privileges.
