Description:
Secunia Research has discovered a vulnerability in My Firewall Plus, which can be exploited by malicious, local users to manipulate the content of arbitrary files on a vulnerable system.

The vulnerability is caused due to the Log Viewer's export functionality saving log files without dropping its privileges first. This can be exploited to corrupt arbitrary files on the system with logging information.

Successful exploitation requires that the user has access to the Log Viewer (all users by default).

The vulnerability has been confirmed in version 5.0 (build 1117). Other versions may also be affected.

NOTE: This vulnerability has been rated "Not critical" as only trusted users should have access to the configuration and logging functionality.
