In VembuBDR before 4.2.0.1 and VembuOffsiteDR before 4.2.0.1 the http API located at /sgwebservice_o.php action logFilePath allows an attacker to write arbitrary files in the context of the web server process. These files can then be executed remotely by calling the file via the web server.

Vembu BDR Suite before 4.2.0 allows Unauthenticated file write via a GET request that specifies a file's name and content.
