Seth Fogie has reported some vulnerabilities in KM Scanner File Utility, which can be exploited by malicious people to cause a DoS (Denial of Service), bypass certain security restrictions, and compromise a vulnerable system.

1) The problem is that the application improperly treats data contained within incoming requests as authenticated. This can be exploited to upload arbitrary files to the affected system.

2) An error in the upload functionality can be exploited to upload arbitrary files to arbitrary locations via directory traversal attacks.

NOTE: The vulnerabilities can be exploited by malicious people to upload malicious executables and compromise a vulnerable system.

3) Multiple errors in the processing of incoming network data can be exploited to crash the application.

The vulnerabilities are reported in version 3.3.0.1. Other versions may also be affected.

Solution
Reportedly, the vendor has released a new version which fixes vulnerability #2.
